Need a little guidance on grinding (self.coffee)

Morning Gentlepeople.

As a coffee newbie I am having some small issues while trying to improve my game. I have a Oracle Touch and subscrube to a local monthly coffee delivery, so my beans change weekly.

My issue is that the grind setting is incredibly different from bean to bean. With my last bag, grind 14 gave a perfect 1:2,5 ratio. With a different bean today, I had to discard two cups before learning that grind size 3 gave me the same ratio. 14 gave me 1:3,5 which tasted rubbish.

The problem is that I got channeling and very little crema.

I guess the questions are: do different beans require completely different ratios or am I doing something very wrong?
Should I accept a very high ratio to avoid channeling on certain beans?
Or should my timer be lower on certain beans?

Thanks in advance for any help and have a great cup this morning!

Counting beans isn't particularly helpful, either, cause they come in a range of sizes. A pacamara bean, for example, is huge, while peaberries of any variety will be tiny. Coffee mills generally sort beans to consistent sizes so they roast well, but you could get coffee from the same farm from 2 different roasters, and each roaster could be buying different sized beans.
