I do really small sample roasting to test a green on a much smaller roaster first. If I really like a green I move to my 2k and create my roast profile at 500g batch sizes. Bryant has a great video on how to scale from 500g to a full batch which we have good results. One thing to remember is he uses many different probes so your RoR curve will most likely look different. There is still some playing around but least I go through less greens at a full batch.

I've been away from my 2k digital for a bit but here's what I've started using. I need to tweak it a bit more, but I did several 300g batches (with NG) back to back and got close to these for some fun sampling. It worked decently, but I feel a few of the samples we tasted weren't full potential.

Hope it helps:
