With all due respect, your inference is irrelevant. Living in the Chicago suburbs, our seasons begin cold. He faces cold bats all of the time and is learning how to respond to balls hit from them. If a bat has been artificially warmed on such a day, the bat will react differently. That IS what the companies show in their studies, after all...and why they are considered illegal for HS baseball, where safety rules the day.
