Question does stall convertor rpm happen between shifts ?

With my setup and shift point of 6200 this is what rpm I roughly see:

35A732FD-D9EC-4A2E-8933-B6FEED0ABFEA.png

I run a 3500 Tight so the converter is not a factor.

But I had a 4000 hard hit FTI that was actually looser with my stroker and my rpm dropped to about 4500 or so at each shift. Lots of slip each shift
