Play around with it man. Just know that the value is 0 when it isn't on cooldown and it's a ridiculously high number that decreases as the cooldown diminishes. Do what you have to do to eliminate the addresses that don't fit that criteria.
Example: After a few searches try NOT using the cooldown and searching for 0 a second time or searching for "unchanged value"
If the cooldown is long enough that it doesn't hit 0 after the first increase search. Try throwing a "value decreased" search.
If you still find yourself unable to narrow down the addresses, well then there is always trial and error. Manually watch it and see what it does. Freeze an address see what happens, toss it if it doesn't do what it expected.
