Dear Shirley
I changed your mgdraw output to formatted, just to read it easily, and I
do not see the problem. Dumping the quantities
          NCASE, JTRACK DTQUEN(1) DTRACK(1), where dtquen is quenched and
dtrack is unquenched, I always obtain dtquen<dtrack as expected:
           1 3 5.26920596E-09 5.31032152E-09
           1 3 1.79176452E-03 2.06275354E-03
           1 3 2.61539157E-04 2.96100159E-04
 and so on.
When I sum all energies for each event, I get quenched around 0.7 GeV,
unquenched around 0.8 GeV.
Maybe you would like to send also your analysis program?
