All sorts.

I keep a spreadsheet of my daily metrics so that I can peruse it for correlations with productivity. I'd like to do that better, and more efficiently.

I've done small experiments to test a claim, essentially praying over an apple slice daily and comparing it's decay to that of a control. I'd like to get "better" and more rigorous at doing that.

do you perhaps wish to become more adept at spotting moments ripe for experimentation in the long run?

This is closest. Basically, I want to put another tool in my toolbox, more then I have a project in mind.

Does that answer your question?
