Hey, Sorry to annoy you all again with a stupid question, but can someone please check this info for correctness/offer advice/commentary? Thanks!

I read somewhere that a rougher NOS Thuringen, when used with slurry, will cut around 5k, but slowly, as it is watered down it will start cutting more like 8k, and dry will polish. I know natural stones vary, but is this a common characteristic? This makes the difference between whether I buy a synth 4k/8k or 3k/8k combo, or just a big NOS Thuringen.

Thanks all!
