Question about weapon speed levels.

Using that formula for some skills on Bui's thread gives different results.

E.g.

Code:

Strafe/Arrow Rain/Inferno/Arrow Bomb/Normal Attack
Faster (2): 600ms (-210ms)
Faster (3): 660ms (-150ms)
Fast (4): 720ms (-90ms)
Fast (5): 750ms (-60ms)
Normal (6): 810ms

.'. 810((10+5)/16) should equal 750.

It is actually 759.375.

What's going on there?

Or is that simply an error margin.

That's that rounding to 30 ms.

Maple doesn't do something every millisecond, but only reacts every 30 ms. Then it decides whether it goes to the next frame of the skill or ends it or sht.

Therefore, it's rounded to some multiplicate of 30ms, which is 750ms in this case. I'm unsure wether it's always the lower multiplicate, the higher, or the one that's closest by (although the higher isn't the case in this one, so I guess we could scrap that).
Seems like it's rounded to the closest multiplicate of 30ms, according to that list (14/16*810 is 708,75, and is rounded to 720 instead of 690).
