I'm just starting out and own a Premier Wonder Grinder like this:

Does anyone have any experience with micro-batches? I'm testing different roasting times and want to use the minimal amount of nibs possible. I don't want to have to use 1kg all at once if I don't have to. I've been experimenting with 2oz batches in my molcajete but obviously the grinding times are limited by what my arm can do (roughly 90 mins).
