Requiring that the reconstructed vertex be within our typical cuts (|Vz| < 55 cm and |Vr| < 2 cm) pushes our tracking efficiency up, but not by the amount we were expecting (see this post).  I was wondering how the efficiency changes with partonic pT, so I calculated the efficiency with requirements on the vertex for various bins of partonic pT.  The answer is that it doesn't change very much...

I'm currently working on the final 3 bins for pTparton = (2, 5) GeV/c, so it remains to be seen how those compare.  The individual efficiencies and the corresponding track distributions are shown below, and the corresponding plots made without QA cuts are attached.
