Shaman Canni Tick

[Matthalas Winterheart]

Recently, Ive tried actually getting canni down pat. I believe my internet connection is pretty solid, so. Im canni'ing at Server mana tick, I stand, and cast..Mana goes up once. Then very shortly after sitting, Im getting a 2nd mana bump.

If Im doing this right, that first mana increase after server tick was the actual Spell gain, the 2nd Im getting very shortly sitting down is the server tick right? I hope thats not confusing. Im just trying to make sure I have this right.
