Oh...and even after being allowed to sit and warm up for 15 minutes, the three measured Colts balls were still underinflated, albeit no longer by as much. Had they not, they’d have to be magic.
Again, do the math using the equation in the Wells report. It’s not controversial, and hasn’t been for centuries. It’s one of those foundational discoveries that the latter half of the industrial revolution relied on.
Start with 12.5 PSI at 71 to 74 F, as the refs locker room was determined to be, and then for example calculate what the ball pressure would be in the Minnesota game last year at -6 F.
The formula for PSI and Fahrenheit is:
P2 =((P1+14.7)*(T2+459.67)/(T1+459.67)-14.7)
It’s not hard. Junior high school kids do it daily.
If Brady didn't have anything to hide he would have admitted he knew the balls felt underinflated!
Every QB tested knew exactly when a football was underinflated and overinflated.
