OH WAIT UR RIGHT, that's why I couldn't do it. Yeah I should have probably done some math before concluding it but yeah, then I've reached the maximum score :)
If you'd like the game to continue indefinitely, you can phase out the oldest numbers as the graph would otherwise become impossible (eg by dropping 2 you can get up to 29,dropping 2 and 3 gets you to 39, etc. as high as you like)
