It seemed that I was jumping wrong for months and months now. I can do then whole story here, but it's already discussed at:

Fred, I'm glad you started that topic, did not know about the "buttontime" I have always beenstruggling hard at the pads, but now the easy ones are all of a sudden the very easy ones

Oh ! I'm glad it helped you ! I wasn't sure of it cauz you can see, some ppl seem to make fun of me there, but now i'm completely sure, i asked a defrag pro, and also if it helped you. So they can just shut their mouth now, i was right !! 

I'm also 100% sure about it: just tapping the jump button brings a faster acceleration than holding it. At first I thought it was imagination, but it is not. When playing a ctf game it does not really become clear, bugt at the pads there is a big difference. Oh and Iḿ talking vq3-physics, I have not tried it at cpm yet.
