So, you are saying that it was indeed correct? That still leaves the 
question why I can't seem to confirm that in the figure I mentioned (red 
and green lines). Also, if you refer to X = lambda*(-ln(U))^(1/k) as 
'proof' for the validity of the formula, I have to ask if 
Weibull(a,Size) does actually correspond to (-ln(U))^(1/a)?
