To be honest as on my other computer cant say if takes into account diffrent way of measuring as in marks a steel plate at back or passes through etc.

This is the one and only source I have seen that gives those numbers for the M829 series and the only two that gave anything close to 700 for the A1 gave the penetration at 1000 m and the only other source that gave A2 780mm gave it for 1000 m and 820 for A3 ? I HAVE seen this comment from tanknet
That Collins..
"downgraded his estimate for the M829A3 from 960mm@2000m to 820mm@2000m.''
so it woud appear at some point that the data I had that quoted Collins at 960 pen was indeed quoting collins it just wasn't up to date and the 820 estimate you are using has been revised once again
The bottom line is everyone with an opinion on this has different numbers so no matter which ones I use somebodys going to say I'm wrong. In many cases what I have done is if there is a variety of opinion where I might see five estimates with a range between say... 620 and 710 I add them all up then divide by five to get the middle estimate or , of they are just too weird I go with Collins and anybody who doesn't like Collins data can go argue with Collins.
As well, the game has a built in variation of 5 - 6 cm for the base average and best achieved penetrations players who are paying attention to messages will see a range of pen that could conceivably cover the high and low estimates out there which are, as I said before just people "guessing" using a variety of math formulas with a bit of " this penetrator or this long and this thick and that ones this and that and THEREFORE........." pontifications. The people who REALLY know aren't telling
