What is Aran's MP usage per minute?

The reason for me asking is with the new alien socket system I could potentially achieve my goal of having very little Mp usage.
I currently have:
3 per 10 base
14 per 4 on my earring
= 228 Mp per Minute
I'm looking for the per minute Mp usage of OS, OS+FB, and FT at speed 2,3, and 4
And whether or not the soon to be released Nebulite could help me get recover about as much as I use or a little more.

Overswing's first hit is 420ms the 2nd hit is 660ms and I think it's 540ms for regular attack all at normal 6. Final Toss is 420ms.
Assuming maxed:
1st hit of overswing: 20 MP
2nd hit of overswing: 22 MP
Final Toss: 25 MP

Boostered speeds (faster 2):
overswingDouble: 330ms
overswingTriple: 510ms
Regular attack: 420ms
finalToss: 330ms

 I think

x+y = 47 casts per minute
xy = max
y = 47-x
x(47-x) = [47x-x^2]d/dx = 47-2x = 0
x = 23.5
23.5 + y = 47
y = 23.5
totalMP = (23*22)+(23*20) = 966 MP a minute
966 - 228 = 738 total MP a minute for Overswing only.
