I can say as an engineer by profession that air is not an ideal gas, so if ideal gas calculations were used to render a conclusion, then the study was flawed.
But the real issue that got obscured was New England's and Brady's lack of cooperation during the investigation. Brady lawyered-up, and likely destroyed or withheld incriminating evidence and refused to give interviews when asked.
This article sums things up rather well about the rationale for the suspension and the fact that New England and Brady acted the way they did and received no punishment is deplorable and sets a very bad precedence against future rule-breakers and investigations.
