it was jumped by a guy from our native simen forum
he said there was only 2 strafes in the air and it was done without prestrafe
but i don't think so

can some1 help me ?
is it 2 or 3 strafes ?
if some1 could measure the prestrafe
it would be better !

one of our moderators analysed the demo a moment ago
the keyboard record said that there were 3 strafes
but he couldn't measure the prestrafe
anybody could help me ?
