Track finding was done using the September 16 build of t00.59.00. The usual 50, 3 and 1 GeV muon events were reconstructed using CFT+SMT. Here are the results:

 run   CPU   eff  fake  misr  fcsq  mcsq  nclu
----  ----  ----  ----  ----  ----  ----  ----
m50    487  .966  .000  .007  21.1   8.1  20.2  (plots)
m03    492  .956  .000  .009  21.7   9.3  20.2  (plots)
m01    450  .897  .000  .010  25.7   9.0  20.2  (plots)
Here are results for CFT only matched with the MC track at the inner CFT layer:
 run   CPU   eff  fake  misr  fcsq  mcsq  nclu
----  ----  ----  ----  ----  ----  ----  ----
m50    304  .966  .000  .000  12.2   5.2  16.0
m03    310  .956  .000  .001  12.5   6.4  16.0
m01    308  .897  .000  .001  16.3   7.0  20.2
Comparing with t00.58.00, there is a little degradation in the fitting for CFT only. The effect is worse with decreasing pT. This may be due to bug fixes in the handling CFT multiple scattering in the reconstruction.

There is still an efficiency loss in the CFT. Much of this cones from problems in the detector simulation. This should be fixed in the next release.

The CFT+SMT fitting looks better but still the match chi-square is still high and has a 1% misreco tail.

Here are the rcp and obs files used in the above studies:
