well i am not sure what you mean by overthinking it. I find although its a simple process, its actually quite the science. An example of much thinking on the subject yielding interesting ideas, is that when you press, you can press to get as most as you can in the first press, getting quite a good product maybe almost eliminating the need for a second press. And second press oil is typically a lot darker if you achieve a thorough leach on first press, so you are left with a very inferior second grade. However maybe a better extract would be to just extract 20 or 30% of it on first press, then have a larger yield second press of pretty good stuff. There are tons of variables. One thing i am sure of for bud pressing, is the smaller the bud nug pressed the better for yield, but tomorrow i will do measured tests.
