Keep on complaining, this is how improvements show up out of thin air...
Previous posts are about a 25m error.
At 540kt, a 100m error is an error of 1/3 of a second on trigger press.
Add on aiming error (parallax), radar range measurment error, ballistic uncertainty (Mk-82 bodies have lots of differences between different lots), pilot's movements between trigger press and bomb release, wind shears, etc...
I have pretty decent results with M2k in CCIP, so maybe you are looking on the wrong direction. Just saying...
