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 Non- Logo 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).
