One of the investigators into the deflategate scandal has insisted that it did not matter which gauge was used by the officials when they measured the PSI of the New England Patriots' footballs in the AFC championship game.

The investigation by Ted Wells found that it was more probable than not that the Patriots had deflated the footballs in their victory over the Indianapolis Colts, which resulted in heavy sanctions against the Super Bowl champions and quarterback Tom Brady.

However, in the report, referee Walt Anderson said that he was unsure which pressure gauge he used before the game and at half time when the balls were remeasured.

Attorney Lorin Reisner is adamant that the discrepancy between the results of the Patriots' footballs and Colts' footballs was enough to prove their case against Bill Belichick's men.

"The question of which gauge was used by Walt Anderson before the game — it just doesn't affect any of the ultimate conclusions," Reisner told reporters.

"The difference in the pressure drops between the two teams was found to be statistically significant regardless of the gauge used.

"It really doesn't matter because regardless of which gauges were used, the scientific consultants addressed all the permutations in the analysis."

Wells has hit out at criticism of his report from the agent of Brady, who suggested that the investigator was biased against the Patriots.
