pressure measurements start on page 72
"For the reasons stated in Section VII.B and described in detail in Appendix 1 based on Exponent‟s conclusion that the Logo Gauge generally reports a measurement that is approximately 0.3-0.45 psi higher than the measurement reported by the Non-Logo Gauge and never produced a reading lower than the Non-Logo Gauge during Exponent‟s testing, it appears most likely that the two officials switched gauges in between measuring each team‟s footballs, meaning that Blakeman most likely used the Logo Gauge and Prioleau most likely used the Non-Logo Gauge to test the Colts balls at halftime. Further, Exponent believes that the results recorded for the third Colts ball tested reflect an anomaly in that, unlike the other Colts balls tested, the reading made by Prioleau is higher than the reading made by Blakeman. Exponent believes that this anomaly may be the result of a transcription error where the measurements recorded were attributed to the opposite game official (i.e., on game day, Blakeman measured 12.95 psi and Prioleau measured 12.50 psi) or a recording error where the pressure measured by one of the officials was incorrectly recorded."
I don't think Tom Terrific will need Barry Scheck for this one.
