There aint nuthin rong with the spit test it works just fine as long as you know what you are doing. When I do my test I just make sure it just evaporates, its not the best way to do it but it works and I know Im not getting the most performance as most but I dont mind. But my Comp 2 runs just fine.

So I ono take caution with the WDT though it aint always accurate.
