One small improvement on the experimental method would be to get someone who you don’t spend much time with to do the randomising. If your gf knows which days are caffeinated she might give subconscious clues. This probably won’t be a big deal in reality but you’re potentially losing some of your blinding.
Thanks! She ordered the bags and gave them numbers but is typically gone by the time I have coffee (we are on different schedules), so this hopefully shouldn’t be a huge issue. That said, this is a good point in the sense that I will explicitly not discuss how I felt that day with respect to the coffee.
This is great.

Replying to your point in a separate comment but will add (with a cite to you) a note about this in the 99% blinded section.
