is the simfast_opt.C file (scrut14 revision 24805 checked out on May 6th) ready to use? I tried to run it, changing the magnetic field to HALF and changed p_min from 0.5 to 0.1 in

fastSim->AddDetector("ScFts", "thtMin=0. thtMax=5. ptmin=0.0 pmin=0.1 pRes=0.05 thtRes=0.002 phiRes=0.002 efficiency=0.80");

Then I tried

root -l -b -q 'simfast_opt.C("llbarsim","llbar_fwp_1-642.DEC",1.64,10000,"pbarpSystem ",88888,"det_full")'

the program runs smoothly but I expected it to reproduce the results from running

root -l -b -q 'simfast.C("llbarsim","llbar_fwp_1-642.DEC",1.64,10000,"pbarpSystem ")'

with the same changes.

However, in the former case, the acceptance is about 1/10 compared to the latter case.
