Grass Tuffs and Saplings per world?

[Darcyre 11]

Basic question, how many grass tuffs and saplings spawned in your world?

My current results (clearing out 8/9 islands so far. Too lazy to go into the marsh):

Grass tuffs: 542

Saplings: 401 (+1 I missed one behind a rock -.-)

And my map ofc:

Wow, how many shovels did you go through! 0.o Great job, is very interesting information and it must have been pain-stackingly tedious, so I thank you, for saving me the trouble had i ever wanted to find this out!
