No, not exactly...
It speeds up the Buff Time you actually see, not the acutall buff itself. See it isn't put server side, at least I don't think. Let me explain a little more:
-The Buff is put on to you, sent to the server to store data.
-Right clicking it is like a hotkey, it sends a packet to the server, exiting the buff.
-When the buff timer runs off (The one you see and the actuall one) it sends another packet, canceling the buff.
Thats why you can't use the 'exact value' with CE or TSearch. If you have a buff that says 30 min. remaining, and you type in 30 for the exact search,
you won't find the value your looking for becuase the data stored in your computer is in seconds not min. and the min. is the time you see and not the time stored in your computer.
Hope this helps...
Note: If the data was stored server side, you COULD NOT get an unlimited buff hack with CE or TSearch, period.
And funny how a 13 year old knows all this

... Don't ask... lol...
