That's certainly true, although it is not hard to find examples which
go over 100 (http://www.babelstone.co.uk/Ludus/Weiqi/FamousGames_279.jpg),
and even the AlphaGo vs Lee Sedol Wikipedia page shows one game
diagram that goes into the 200s.

Possibly.  I certainly have very little expectation that a proposal to
complete both sets to 999 (or even 399) would have any chance of
success.

I am currently working on a proposal for the triangle and square go
markers, and am still considering the best approach to the circled
numbers.  Any feedback would be most welcome.
