Just some noob questions

With the crafty plus I am using the factory settings. When I turn it on, I wait for the first temp to settle, then I take 2-3 draws.

Then I bump it up to the next one, and take draws from it for about 3-5 minutes before fully boosting it. I keep taking draws from it for two minutes, and continue until it almost shuts down, then I do anywhere from 2-5 minutes on the lowest heat again.

It can be up to 20 minutes sometimes.

Is this overkill? Could I be getting the whole dose in 5 minutes, and the other 15 is just wasting time and battery?

Can you go straight to the turbo boost, and then still get extractions at the lower temps later in the session?

What should the ideal session and time and heats be if I can take decent draws, and hold them for 10 seconds, then go for another draw.

I'm being treated for muscle pain/cramping and nerve pain.

Any help or tips would be greatly appreciated, so thanks in advance.
