My understanding is that balls are inflated to 13 psi, that 12.5 is the min and 13.5 is the max. At 13 psi the balls would have tested at approx. 12+ psi. by this test. Also that a temp alone would cause the balls to lose 1 psi with a drop in temp from 92 to 50 degrees. Also was not discussed was water saturation and time of temperature and moisture exposure. I assume the balls are kept under a cover during rainy weather and I have seen attendants towel drying balls on the sidelines. Why didn’t the balls the Colts used lose pressure or why weren’t that checked if they didn’t? Was this “scientific test” done by any chance at MIT in BOSTON. Of course we would still be having all this discussion if NE didn’t have a reputation as cheaters.
A lot of folks got the science wrong because they didn’t include atmospheric pressure + the PSI of the ball above atmospheric pressure.
Article in NYT explains what scientist are saying. NFL is using Columbia Physics prof in their investigation.
Additionally the NFL never recorded the PSI of the balls a pregame or at halftime. IOW no records of anything as per Blandino. No proof anything was done to balls.
My guess refs game the balls the squeeze test and allowed balls from both teams into game, then Colts did sting balls were adjusted and Patriots go out and out score Colts 28-0 in second half.
