Thanks! I'm always pleased to hear that other people find this stuff interesting or useful.

I do particularly enjoy the tracking part. My brother seems to think I'm some sort of nut about it. But I find that it's interesting to look back and see what I was doing at some point in the past. It's also useful in the short term: More than once during the pandemic I've been able to look at my notes and say, "Ah! The reason I'm feeling tired is that I haven't taken a de-load week in over six weeks."
