I like to rev up to about 1.5 or 1.75, then slowly release the clutch up toth point where it grabs on. You should know when it fully grabs on, cuz you won't feel the slipping any more. You have to know how much you can release the clutch before it starts touching. Once you have this position memorized, just rev up, release quickly up to that critical distance for the clutch, then slow it down by countering it with your ankle, then release it with your leg. If you release too slowly, it'll slip. If you release too quickly the clutch might chatter.
I use the clutch with the heel up, so my whole leg is depressing the clutch, that way I can use some ankle while releasing the clutch to get that perfect shift.
You'll get used to it. Just practice a lot.
Also some weird things will happen after you get the hang of it. Just experiment
