Hi Felix,

the numbers I quoted in one of my post, i.e.

Efficiency | sigma(eta_c) | sigma(phi)
pion:
27.04% | 11.74 MeV | 3.61 MeV
kaon:
27.29% | 11.94 MeV | 3.55 MeV

is for 2000 events statistics, and producing higher number of events is rather time consuming. And here statistical errors for efficiency are around 1.3%. I plan till Monday to produce 5000 events with pion hypotheis, but it will not decrease errors below the difference between pion and kaon hypotheses I quote here.
