Question About Maxed Assassinate skill

I tired of SB + BS macro at mini boss/ run it's slow but it has the highest chance to avoid any attacks. I have no motivation to lv up Shadower anymore and don't feel like to make a new class. Haven't level up for ages. until I decided to put the 7 sp i saved for shadow shifter into assassinate, a uncharge assassinate can do dmg 8~10k 3 hits + final and a fully charged can deal up to 28k~ 39K 3 hits + final but 6 sec charge. I wanna ask how much dmg a uncharge assassinate can do at max lv? Please help

Max Assassinate:

No charge:
1st - 600%
2nd - 600%
3rd - 600%
4th - [600%] + [250% @ 90% chance]

12sec charge (8 secs after class balance patch):
1st - 3000%
2nd - 3000%
3rd - 3000%
4th - [3000%] + [1250% @ 90% chance]

Chargeup works like:
[Base damage (600%)] * { [Dark Sight Time (12seconds) / 2] -1 }
--> Read: every 2 seconds in Dark Sight, the multiplier is raised by 1 (1x,2x,3x,4x and max 5x)

I know Assi Chargeup works a little bit different (Fiel once posted how it really works, but that once is -way- too complicated to be used in-game), but this method works for 90% correctly, and most people understand it also!

Wooh thanks a lot !

[COLOR="orange"]Has it been confirmed if the 8 second charge will do the same damage as the 12 second charge?
And the formula would instead be {[Dark Sight Time (8seconds) / 2]+1}?[/COLOR]
