The tape I'm using tends to leave a slightly noticeable residue or slurry on my 8k. Is this indicative of bad technic or is it normal? Also will this affect my edge's contact with the grit?

I've been practicing with a few stones to get my bearings and a cheap razor recently and wanting to be careful before I move up to my nicer razors.

I should also note that after I run the razor through 4k/8k and ch12k, the edge is nice and smooth and pops hairs with ease.
