What really happens during a 4L60E shift ?

[INTHERED]

I ran at the track last weekend and dataloged RPM, MAF, TPS%, Force Motor
Current and Last Shift Time and I was surprised to see that each shift was
0.5 sec long even though my entire Desired Shift Time table was set to 0.2
I also noticed that before the trans actually shifted the FM current started to
change to the shift value while the RPMs were still increasing. I also noticed
in this same area that the MAF numbers were decreasing even though the
RPMs were increasing and the TPS was 100% ? What should the transmission
and TCC be doing during a WOT shift ? Is there a tuning method that makes
the transmission shift faster and more precise ?

Thanks >>>>> INTHERED

P.S. >>> I have heard of people setting the shift MPHs to zero and using
only the RPM settings would this technique be better for racing ?

The MAF is slow to respond (which is why it is ignored
in non-steady-state) but just running up RPM may not
increase airflow; if your real VE is taking a dive before
shiftpoint for example, or if there is some release of
load (such as shift flare) or if TM has pulled back spark.

TM is turned off, the VE table is steady at 98, I don't know about
shift flare I wonder if it could be blower belt slip ?
