If he has been playing like 10 hours a week and bumps it to 30+ hours a week, I don't see any reason he can't still make significant improvement.
I think 650 to 700 in a year is pretty doable. With smart practice I bet he could do even better.
The hill only gets steeper, though. And 775+ seems...
And here's a Python version using SciPy. There's a cumulative distribution function, so I can avoid the looping (ARRAYFORMULA w/ SEQUENCE) that I had to do in the spreadsheet. Both cumulative and summed distribution work out the same as you'd expect.

If the shaft had similar bending stiffness to one with higher end mass, this is probably true. Generally CF shafts are higher bending stiffness. Maybe an LD wood shaft would be best?
