Harry and Andy are both right and make good points. Yet some of your question remains and we have no quantitative answer. How high is too high and must be corrected?
As a touchstone, consider this: If the tail is at or above 72 (71? 70?) inches, the degradation to crosswinds isn't too bad. At 68-69 inches, it's getting unpleasant on a strong crosswind in a Coupe with two controls or with an ERCO rudder pedal kit. Somewhere along the way it gets into the dangerous zone (which moves, depending on conditions). If I were one or two inches high, I'd just wait till the donuts settle and not sweat it. Three inches high and I'd be thinking about disassembling the darn things to take out the unneeded spacers. Four or more inches high, I'd never let it get out of the shop. But remember, we DON'T know the answer, really. Quantifying this is just guesswork. No one has ever tested it except for Fred and his team, maybe. Probably not even them, I'd guess.
