True. But we have hundreds of facilities we can go to to practice if we’re not happy at one place. Where does an ‘independent contractor’ of professional golf go to make their living if they rebuke the PGA TOUR?
So, if we "maintain" the temperature of the balls at the same level (degrees) at which the manufacturer or the USGA or whoever tested them, then we are not violating the rule. Right? But if we "deliberately alter" the temperature of the balls by heating or whatever, then we are violating the rule. Does that seem correct? So now we need to know what the "official" USGA temperature is, so that we don't violate the rule. Right?
It is worth noting that the new rule 4.2(a)2 differs from the old Decision 14-3/13.5 in that the decision distinguished between warming before and during a round, whereas the rule says it is illegal whenever the ball's performance characteristics have been deliberately altered,
The advert is correct in that the rule has been revised but not in the way they say
