Maxx Posted December 2, 2002 Share Posted December 2, 2002 The test had the following parameters: South, Damp, June 1944, Hot, Midday, Regulars. Test track was a 800m stretch of either scattered woods or clear terrain. 10 tanks per type per test, 5 tests for each type in both terrain types. That works out to 50 tests over 800m per vehicle, per terrain type. Data shows percent of tanks that IMMOBILIZED due to bog. Clear: ...T34/76 T34/85 Panther Tiger MkIVJ 1.....0........0.........0.......10......0 2.....0........0........10........0.....10 3.....0........0.........0.......10......0 4....10........0.........0........0.....10 5.....0........0........10.......10......0 Scattered Woods: ...T34/76 T34/85 Panther Tiger MkIVJ 1....30.......40.......70......100.....30 2....10.......40.......30......100.....80 3....10.......20.......70......100.....50 4....10.......60.......50......100.....80 5....40.......50.......50......100.....90 Note: The majority of Tigers in scattered woods immobilized within the first 150m of travel. All movement orders were 'fast'. Initial tests using the 'move' order show even higher percentage chance of bogging to immobilized in scattered trees. Sorry for the poor formatting, I don't know how to insert tabs. [ December 02, 2002, 02:15 PM: Message edited by: Maxx ] Link to comment Share on other sites More sharing options...
Vanir Ausf B Posted December 2, 2002 Share Posted December 2, 2002 There is no need to test different vehicles against each other sinse the chance of bogging is directly derived from the ground pressure rating. Just compare ground pressures. Link to comment Share on other sites More sharing options...

WWB Posted December 2, 2002 Share Posted December 2, 2002 I think more is involved than ground pressure ratings, but I cannot confirm this as fact. Two key factors not mentioned--experience of the tanks and speed at which they were moving. WWB Link to comment Share on other sites More sharing options...

However, since they are not characteristics of the particular vehicles being tested it would be easier to test for them by using all vehicles of a single model. Same with terrain.

WWB Posted December 2, 2002 Share Posted December 2, 2002 I see them now, was not too clear. Experience is definitly a factor in CMBB bogging chances according to BFC. Look at the huge changelog if it is still up. I am certain movement speed is a huge factor. Run the above test using fast or hunt and see what happens.

demoss Posted December 2, 2002 Share Posted December 2, 2002 I am certain movement speed is a huge factor. Run the above test using fast or hunt and see what happens. He said that it was with fast, and that move resulted in even MORE immobilizations (!!!). That, if true, would probably be a bug. Link to comment Share on other sites More sharing options...
Maxx Posted December 2, 2002 Author Share Posted December 2, 2002 Yes, 'move' seems to have more immobilizations due to bog than 'fast'. I think this might be due to the tank being in scattered woods much longer than with a 'fast' move. In other words, bogging is a function of time in the terrain, not discrete coordinates (if such a thing is used in CMBB). Link to comment Share on other sites More sharing options...
PeterX Posted December 2, 2002 Share Posted December 2, 2002 He said that it was with fast, and that move resulted in even MORE immobilizations (!!!). That, if true, would probably be a bug. I've noticed that employing the HUNT command seems to result in fewer immobs than either MOVE or FAST. The impression is that MOVE is the most bog prone. I wish BFC would ditch the Ground Pressure/PSI ratio and subsitute a general flotation rating like Very Good, Fair, etc. It would incorporate all the relevant factors including, perhaps, drive train reliabilty.

In other words, bogging is a function of time in the terrain, not discrete coordinates (if such a thing is used in CMBB).In CMBO, the faster you went, the less likely you were to bog, given an equal distance traveled. I don't know if this is still the same in CMBB, but I intend to find out Link to comment Share on other sites More sharing options...
WWB Posted December 2, 2002 Share Posted December 2, 2002 No, I am referring to the CMBO->CMBB changelog. The massive, 50 pager that they posted after the demo came out. Time in terrain would have an effect to be sure. We might need to look at bogs per second of movmement. One other issue with the test is that 10 is far too small a sample. As Matt has said, any statistical test with fewer than 100 cases is not a valid test. WWB Link to comment Share on other sites More sharing options...
Maxx Posted December 2, 2002 Author Share Posted December 2, 2002 Okay, same test, only this time the 'move' command was used instead of 'fast'. Every other variable was the same. Again, these are done in lots of 10 over 5 test trials. That is 50 tests over 800m per vehicle, per terrain type. Data shows percent of tanks that are IMMOBILIZED due to bog. Clear: ...T34/76 T34/85 Panther Tiger MkIVJ 1....10........0.........0.......10......0 2.....0........0........10.......10......0 3.....0........0.........0.......20......0 4.....0.......10.........0.......10.....10 5.....0........0.........0.......30......0 Scattered Woods: ...T34/76 T34/85 Panther Tiger MkIVJ 1....20.......30.......70......100.....70 2.....0.......50.......70......100.....40 3....10.......50.......60......100.....40 4....30.......10.......20......100.....60 5....10.......20.......50......100.....70 Note: I don't see alot of difference between 'move' and 'fast' as far as being immobilized due to bog. Perhaps 'move' is a bit worse than 'fast' for a Tiger in clear terrain. [ December 02, 2002, 02:15 PM: Message edited by: Maxx ] Link to comment Share on other sites More sharing options...

WWB Posted December 2, 2002 Share Posted December 2, 2002 Hmm, yeah, it is not in there. I do recall Steve saying they were going to make bogging dependant on experience, but it might not have actually made it in. WWB Link to comment Share on other sites More sharing options...
PJungnitsch Posted December 2, 2002 Share Posted December 2, 2002 This is how the east front MMP rankings would go: Panther 150-155 BT-5 175 T-34/76 174-186 Tiger II 184 Tiger I 185-192 KV-1 208 Panzer IV 184-191 T-34/85 196 Panzer III 220-232 BT-7 240 JS-I, II, III 245 Universal Carrier 253 Sherman VVSS 282 Elephant 370 PzIII and PzIV do not appear to include Ostkotten. Early war floatation rankings shouldn't change much from NGP ratings. Late war they would though. Link to comment Share on other sites More sharing options...
Maxx Posted December 3, 2002 Author Share Posted December 3, 2002 Result's for hunt: Every other variable was the same as the 'move' and 'fast' tests. These are done in lots of 10 over 5 test trials.

GJK Posted December 3, 2002 Share Posted December 3, 2002 So per the tests, a Tiger is going to bog in scattered trees every time. Is that realistic? Link to comment Share on other sites More sharing options...

Uedel Posted December 3, 2002 Share Posted December 3, 2002 If the results of the Test would be realistic Germany would got have real difficuluts placing Tigers on the Front, think about a Tiger Factory every 2 Km on the whole front, because u dont wanna make it more then 2 km´s with a Tiger lol Link to comment Share on other sites More sharing options...
Eden Smallwood Posted December 3, 2002 Share Posted December 3, 2002 Hey guys; nice tests, ( I think ). It's just me, Mr N. L. Retentive programmer, poking around with the UBB code... It looks like we can preserve tabs and spaces with a CODE block, fwiw.

Hurricane Posted December 3, 2002 Share Posted December 3, 2002 I might remember wrong, but wasn't the risk of bogging smaller in scattered trees than clear in CMBO? I think this was explained by the fact that roots and stuff would prevent the ground from getting muddy. These results, OTOH, clearly seems to show that you in CMBB should stay out of scattered trees. Link to comment Share on other sites More sharing options...
GJK Posted December 3, 2002 Share Posted December 3, 2002 Eden: Did you just use a "blockquote" to keep the formatting? As for the tests: I don't like the thought of something happening (be it ill-wanted or well-wanted) 100% of the time. The bog rate of a Tiger may have been high (I don't know) but I can't believe it's going to bog (and immobilize!) 100% of the time in scattered woods. Hopefully BFC can confirm and debug if necessary. Link to comment Share on other sites More sharing options...
thewood Posted December 3, 2002 Share Posted December 3, 2002 Are there any results for how far Tigers got into the trees before bogging? It may look like it bogs 100% of the time, but if the stretch of trees is long enough, any thing will bog eventually. I assume the Tigers don't bog as soon as they hit the trees, but after being in them for a while. Link to comment Share on other sites More sharing options...
