How much would be an average edible dose?

Trying to gauge what I should take, seems like I’ve heard anywhere from 5-10mg to 500mg. I have a relatively higher tolerance, I’ve been smoking for over 10 years, but never was big on edibles beaus smoking was so straightforward. I’ve taken them a few times but never really had my socks blown off, and most the time back then they weren’t specifically dosed , jusy weed. I’ve taken some chocolates since, but the ones here in Florida aren’t very strong, I’ve had some THC-a gummies that got me feeling pretty good, but not blitzed off my ass. That was like 50mg, but I don’t know for sure. Anyway, I have like 90mg or so of RSO, 8-9 10mg RSO capsules. What would be a good dose to start with, and have the least risk of wasting it? Id rather have one big dose that really hits, than two doses that didn’t really get me where I want to be, but since I’m not very familiar with edibles and RSO in general I thought I’d ask for some advice, though I know it does vary a lot.
