The min water paste yielded 1.1% of mescaline citrate xtals (I usually get ~1.4% with this powder) and produced the darkest, greenest EA I have seen.

Where's the rest? I pulled the spent paste (that is a sticky blob at this point) and significant product is coming through.

Therefore, I preliminarily conclude that min water is not ideal. Not sure why. Maybe a little extra water helps transport the mescaline into EA, or maybe something else.

I still want to try to set the water amount relative to the paste texture to make the process more repeatable. The point at which the min water paste forms could be used as a standard reference. Next, I'm going to try min water paste, and then add 50ml of water. Idea is to keep water low, but have enough so the mescaline flows freely.

The very dark color is interesting. I think calcium carbonate with more water in the standard tek is breaking down some of the chlorophyll. Also, there is this from an old patent (attached).

So instead of the microwave (which is now questionable for lowering yields slightly). Perhaps placing the french press in a hot water bath for a few hours will result in a cleaner EA extract deeply tinted with chlorophyll. I'll try this also.
