I do agree that in my case anyway at my skill level it's not likely to make a whole lot of difference.
The question is, will losing the exact 2:1 length/width ratio cause the table to play "funny"? I'm not looking to make it play like a Diamond, just acceptable in terms of how it played originally. In reading opinions in "Talk to a Mechanic", especially in the dustup on the subject between Trent from Toledo and Mark Gregory, the issue is no more settled than Ford vs. Chevy at a monster truck jam.
You hate to pay top price for a fully restored table only to have to drop another 3K or whatever to get Mark Gregory to come straighten it out. But then again, it's also hard to believe that all the old Gold Crowns out there have had complete rail recalibrations done when the rubber got replaced. In fact, I'm sure most have not and nobody complains about how they play so there you go.
