No, you threw numbers saying something you cannot prove, and you assume
we should trust your words. This is stupid.

If I cannot reproduce, your point is null and your claim is absurd.

This is pure absurdity.

Let's go forward, will you ? This has everything to do with what you
said. You claim that since every change produce random effects on every
computer, no benchmark is worth, no proof is worth being showed.

If you want to say anything, please give valid arguments.

This is all absurd and stupid IMHO.

I won't repeat myself. You are intelligent to understand and no playing
around, I hope.

Blabla, playing around won't make your point valid, I say your point is
void, because code is assumed to not contain anything useless, so
nothing useless will _ever_ be added, so don't even consider it nor talk
about it. Is it so hard to understand for you ?

Debating with you is really tiring since you make so many efforts to
show that you do not understand what people say while you obviously do.
