Incanter's Flow direction tracking

[akeon1]

Question We need a way to track if buff/talent "Incanter's Flow" is counting up or counting down.
Is this possible or can it be made possible?

Description:
Incanters flow is a talent that gives the mage a 'flowing' buff.
Every second the buff gains a stack increasing your damage delt, up to 5 stacks
Once the buff reaches 5 stacks (after 5 seconds) it then begins dropping down 1 stack every second, lowering the damage bonus % of the buff.

So it would look like
--Start combat
1 second in = Incanter's Flow buff is now at 1 stack (4% damage bonus)
2 seconds in = Incanter's Flow buff is now at 2 stacks (8% damage bonus)
3 seconds in = Incanter's Flow buff is now at 3 stacks (12% damage bonus)
4 seconds in = Incanter's Flow buff is now at 4 stacks (16% damage bonus)
5 seconds in = Incanter's Flow buff is now at 5 stacks (20% damage bonus)
6 seconds in = Incanter's Flow buff is still at 5 stacks (20% damage bonus)
7 seconds in = Incanter's Flow buff is now at 4 stacks (16% damage bonus)
8 seconds in = Incanter's Flow buff is now at 3 stacks (12% damage bonus)
9 seconds in = Incanter's Flow buff is now at 2 stacks (8% damage bonus)
10 seconds in = Incanter's Flow buff is now at 1 stack (4% damage bonus)
--cycle repeats until combat ends.

Being able to know if Incanter's Flow is on the "upward" leg would be hugley beneficial.

For example we might want to cast a spell (meteor for argument sake) at 4 stacks.
- but if Incanter's Flow is on the upward leg we know it will hit 5 stacks so we would hold off.
- if Incanter's Flow is on the downward leg we know it will hit 3 stacks next so would want to burn the spell before then.

Custom func, timer on buff applied? Ergo cast at 3 seconds in, use FoF ice lance at 5/?
