But my procedure has been always 100% the same except for the loaded engine at
program start. Also I always reboot before I start a match. The issues you
address were valid in match-1, match-2 and match-3, still there is this
difference of 4.7%.

What happened to Xinix? I can not believe your ranking, has fatherhood troubled
