I've never done alchemy research before but I thought I'd give it a try with the new pre-tempering potions for enchanting out. The process wasn't too difficult to figure out and I like the idea a lot, although the mental fatigue seems to build up pretty quickly.

I researched 3 potions, but I ended up getting the same potion on my 1st and 3rd try. Is there any way to avoid that, and is that expected behavior? When you finish the research it says you commit it to memory, so I was surprised that I got it again. Do you not accumulate knowledge of these recipes so that you do not research the same recipe again?

If I am not mistaken, the commit to memory message means that you can then write it in a recipe book if you wanted to? I also really like the idea of the system but wished it worked a bit smoother to avoid those like you said.
