....I seem to remember a similar study being done before, but I don't 
remember where it is nor whether it was pre- iTPC. What I can do relatively 
quickly is take some Run 19 AuAu200 data and process a few hundred events 
with and without those two RDOs and look at the distributions of lost tracks. 
Yuri may actually be more efficiently set up for a such a study than me, but 
I understand he's got plenty else on his plate.

Carrying those inefficiencies through to impact on loss of physics would 
likely require PWG/analyzer involvement.
