...yeah well, your explanation is totally throwing me off; 1e& - "ah"!?
...since when do we split up 16th notes like this? Unless its the "ah" of 2.

idk man.
Nah fam. I think some of you are trying to hard to grasp it. No pun or anything. I stated that i set spaces to let u know the grace notes of the flams. Its still straight 16ths. And i didnt know they werent exactly on top of the stickings.
So every right or left hand sticking before the accent is a grace note(besides the downbeat of the second measure of the pattern). So lets see if this is better:
lRrrrL llllR rrLll lrlrlrlr / LrrrL llllR rrLll lrlrlrlr
or llrrllrr
I tried to get the count right above the stickings but i couldnt so ill post that seperately. The bold is the accent so you know theres a flam. Here it is without the spaces.
1e&a 2e&a 3e&a 4(32nd single/double rolls) / 1e&a 2e&a 3e&a 4(32nd single/double rolls)Or like i said earlier you can start the rolls on the & of 3.
