One reason why I wanted to fix this top is that it was great when i made it (2010) and it's even better now. It has been heat treated and is very stable. Now that I scraped off the old wood grounding it rings longer too. As for the frequencies I also got to check what I already kind of knew; M5 did not change with the stripes, neither did M5 change when I evenly trimmed them, weight/stiffness ratio stays the same when placed in the middle like this. This is the key to tuning/optimizing bass bar and violin plates in general.
