As we can see BR ratio in the pole is OK.
Also dGamma/dM is working fine.

I put distributions of Delta mass drawed for 1mln generated events directly from this macro (not in Log Scale).

index.php?t=getfile&id=6670&private=0

This looks nice.

But for mas of (proton e+ e-) one can see

index.php?t=getfile&id=6666&private=0

Question is: How large should be statistic to get smooth shape of Dalta tail? Because 1 mln is not enough as we can see.

By the way i thought that main goal to use flat gen was to make tail smoother. Do we have reversed result?

e+e- invariant mass looks quite smoothly.
