I just edited the most recent version of Recount [47214] to support toggling of the synchronization feature. At least I hope so. I had no chance of testing it since our raid was cancelled tonight.
So if your computer crashes and your monitor explodes, it's not my fault.
It may have disabled syncing alltogether, I don't know, my only test was in an AV game where I'm note sure if syncing would have worked at all.
Anyway, you just have to do a /recount sync to toggle it on/off (presumably).
Also it *should* save between game sessions (on a per-character basis).

I've only changed Tracker.lua and Recount.lua, so I only included these two files and I urge you to make a backup of your original files before unpacking them.
Again, if your house crashes or your brain explodes, it's not my fault.
PS: While I was editing the file, I noticed that there was already a variable DisableSyncing entered in one if statement, but couldn't find another occurrence of this variable.
