In addition, Exponent determined that when the Logo and Non-Logo Gauges
measure an identical pressure, different readings are produced. According to Exponent, the Logo
Gauge produced readings that were generally in the range of 0.3-0.4 psi higher than the NonLogo
Gauge. However, for a given set of measurements, the differential between the gauges
generally remained consistent when compared to a calibrated gauge. In other words, in the short
term, both the Logo Gauge and Non-Logo Gauge read consistently, though differently from each
other. Exponent?s experimental results were aligned with the measurements recorded at
halftime, which indicated a consistent gauge-to-gauge differential of 0.3-0.45 psi. Exponent
relied upon this information, as well as the fact that during the testing the Non-Logo Gauge
never produced a reading higher than the Logo Gauge, to conclude that Walt Anderson most
likely used the Non-Logo Gauge to inspect the game balls prior to the game, that Clete
Blakeman most likely used the Non-Logo Gauge and Dyrol Prioleau most likely used the Logo
Gauge to test the Patriots game balls at halftime, and that the game officials most likely switched
gauges before measuring the Colts balls at halftime (with the one anomaly described above).
