That's not the problem at all, you're forgetting the most important, you will never byte match the values reported as uploaded and downloaded, so it's just a matter of time until you report lower values than the previous announce.
Example:
uTorrent reports, 10 mb uploaded
mRatio reports, 15mb upload
uTorrent reports 11 mb uploaded
It's over ...
No matter what you start first or the amount reported, if you run the same torrent on uTorrent and mRatio at the same time you will end up reporting lower values, even in your luckiest days.
Any tracker that checks that will spot you in 2 or 3 announces.
