IRL Excalibur has a Circular Error Probable [CEP] of 6-10 meters depending on who you ask. What that means is there is an expectation that at least 50% of the fired rounds should impact within 6-10 meters of their intended aim point [the submitted grid coordinates of the target].
What you find in real life is that the Excalibur reliably goes where you tell it to go, but where you tell it to go is not always where you actually want it to go. The average maneuever shooter soldier [not FO] with binoculars achieves a target location error [TLE] of 300+ meters. Meaning there are plenty of times Excals impact a great distance from where you expected it to land. With an LLDR that number drops to 10 meters TLE.
I think when they nerfed the EXCAL they tweaked elements of the equation which affect the CEP-- they could go even further if equipment and quality of troops realistically affected TLE as well.
