They design football helmets, they know far more than you or I.
Yes the used the premise of how would a football inflated to 12.5 psi would react to the climatic conditions present that evening the results showed that you would see a definite drop in psi. The experimental results the came up with were very close to the halftime results the officials observed.
Perhaps you weren’t watching the game, it was played in a DRIVING rainstorm the game balls were SOAKED, we had > 1 in during the game. So their method was sound.
I will point out the real problems here, The NFL had no recorded psi for either team Pergame, so there was no baseline for comparison with the
halftime measurements. Frankly the Wells report should have focused of the lack of process, but that isn’t what they were being paid to do.
So like all lawyers the made the case their client Wanted made.
Wells isn’t an independent investigator, he is a hired gun for Goodell’s, he defended the NFL in the concussion lawsuit, the firn he hired to run their science experiment was hired bt Tobacco firms to ‘prove’ that cigs don’t cause cancer, product lawsuits against auto firm ect.
The N FL had an ananda and paid for the desired result.
Alright, what's so hard to understand the math here?
(1) There were probably 60 non-special teams' plays in that first half (by both teams together)
(2) The two teams supplied 24 (total) balls.
(3) On any given play of those 60, 96% of those balls are secured on the sideline in bags that keep them relatively dry.
(4) If each of the 24 balls were used equally in the first half on those 60 plays, then each ball averaged 2.5 plays...FOR THE ENTIRE HALF!
(5) Even when those balls may be used for 2-3 plays over the entire half, they are never used in a wet game on consecutive plays. They are shuttled out to the ball boy who dries them with a towel.
(6) So EACH ball, on average, has 2-3 minutes of wet exposure THE ENTIRE HALF!
(7) When I saw the YouTube PSI check "experiment," it was on a wet ball. Yet I guarantee you those balls when checked at halftime, were no longer wet...because the ballboy did his job the entire first half...drying them as they came off the field.
So are you trying to say that 2-3 minutes of wet exposure, plus whatever pregame warmup time on TWO or so of those dozen balls, is such a monumental difference? REALLY?
If so, you flunk basic math. And that's where these "engineers" flunked basic principles here. They were so into elemental dynamics here that they totally ignored and negated overall context.
