Championship 2007 back testing results is different between build 208 and 209

 

Can anyone explain why the back testing results of the Championship is different?

First I uploaded the EA to the Championship website, and I got the testing results for my EA (I printed it to make my own documentation) that was based on the build 208

After a few days I got another email saying that the EA was approved (this was maybe the third email even I did not changed the EA) so I checked the back testing results which generated by the championship website and I got different results , different number of trades, profit, percent wins all was different

Can someone help me in this issue?
