All good points Letekro. They are interesting charts.
Ran into this interesting link searching for some help.

Your statement "But PSI rises quickly" has been what I have personally focused on within the charts.
Using simple methods I've tried to understand what the average reacclimation rate was. I would have expected that regardless of which gauge was used the rate of psi gain should have remained similar. But when looking at the charts I find a difference. (Again, I'm not a physicist) Not sure if it is significant and means that their game day simulation demonstrates that even in a "controlled" environment results will vary or if the results are not significant and , of course, OR I don't know what the hell I am doing.
Patriots chart: Rate of PSI gain = (2nd Avg psi - First Avg psi)/ (2nd Avg time - 1st Avg time)
Same for rate of Psi gain between 2nd and 3rd Avg start times.
The change in the rate of psi gain for the Patriots footballs between the 2nd and 3rd measurements almost doubled when performing the test with the Non-Logo gauge compared to the similar start times using the Logo Gauge.

The Colts rate change between the 1st and 2nd and the 2nd and 3rd vary by 15 and 22 percent.
