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."
In Saint Louis that summer (1920), three cowboys were ushered into the Yankee dressing room to meet Ruth. They told him they had ridden three days on horseback to catch a train in Wyoming. "Babe Ruth," one of them drawled, I’d have ridden all the way to Saint Louis to see you hit them home runs." - Kal Wagenheim
