edit only the second half? the series of curves
in the single-curve only changes the met? with pi values? low, increasing with gradualit
you touched too soon, and then increases with gradualit?, not right now 13%, but began perhaps with a point to 3, one 6, one 9, and then 12/13%
especially check the 2d, in the last curve c'? a peak towards the top, which is not good, you should try to keep the curve ir? sweet can
