under the assumption that both teams inflated their balls to a similar psi, under the same inflation conditions

There are zero reasons to believe those assumptions are true.

or some reason the Pats balls (at a home game) reacted differently to the same weather conditions

All we know is that the Pats balls were under the limit and the Colts balls met the limit. To my knowledge, there has been nothing released/leaked about any decrease in pressure in the Colts balls, just that they were within the rules.

The Pats may or may not have done something untoward, but the only reason so many people seem to think it's a slam dunk is that they're misinterpreting the information that's out there.
