I agree there`s no way anyone would get to that speed with only 2 perfect zones. He must have had 155 imperfect zones, which would mean there`s no way he could have reached 157 without blowing up. Say he only lost 1 point of shield energy on each zone, and add the 20 shield points for the 2 perfect zones, then the max he could have got to is 123 I think. I think that logic is right.

I think it`s definitely worth an email to SCEE/SL as Wipeout HD is an amazingly "clean" online game and should be kept that way. Hopefully it`s just a random occurrence and not a glitch in the game that can be exploited.
