vg tincture question

so i posted this in the concentrates/extracts forum, but i havent gotten any replies an im gonna do this tonight. i have 42g's of vaped bud an 16 oz pure vg. my question is since it is vaped how many grams per oz would be good for a potent tincture? i was thinking 3-1, but as its my first time trying this i wanted to get a little in-sight and google was less than helpful.

Nobody uses pg/vg to extract...its not efficient
Nobody in c&e messes with already vaped bud..

i know its not efficient, but it does extract an since its weed ive already used im alright with wasting some of it to try to make a tincture. i dont wanna use everclear tho.

Its too thick, super low dissolution rates. You have to heat for an extended period. You end up degrading a lot. It will also not be very concentrated.

We make hash oil out of a preferred method and saturate the vg with the oil

I throw away my vaped bud... so.... I mean I don't mean to be a negative nancy but yea

i can get my hands on wax if using that with vg would be better.
