The only "evidence" I can submit would be contrary evidence... I have pulled apart many wonderfully stable pianos for restringing and found amazing gaps at the flange. Have also wedged badly fit blocks and found little improvement in stability. In general, over the years, I have found little correlation between block fit and stability. I know, I know, this is all anecdotal, but I think many of us have had similar observations, and would like to see some "hard" experimentation to find out whats really happening. Note: One of my favorite parts of the rebuilding proccess is getting that perfect flange/block fit. (didn't want anyone to think I slop through the job!)
