Are you joking? Can you get a list of the "reported" distances on some homers over the past decade or so? There have been many balls that went 470+, including at least a few hit by easy swinging Miguel Cabrera. Let's not be naive and think baseball can't adjust this game like a puppet on a string. Did you read this from Popular Mechanics?

That's a 10 percent performance difference within MLB's own specs and could mean the difference between a lazy fly ball and a home run."
"The inference is that in the dead of the night the under-secretary of the club owner sneaks to a private telephone, summons the manufacturer, and bids him pour a little strychnine of digitalis into the old apple to make its heart action quicker. The factory gets out the ball bearings, the block rubber, and the go-juice, and the home run epidemic follows." - Paul Gallico
