You haven’t automated that door jamb yet?To err is human. Not exactly a “log book” but there is a door jam in my daughters closet that has record of how tall she was with a date and weight next to the height line. Not that I get anything out of that data or that it makes anyone safer but I can guarantee it’s a more accurate representation of her growth through out the years than I could put together by memory.
Not a chance I could ever remember every load combination I have put together over the last 37 years.
Like back in 2007 when I set out to find a minor SSR load one afternoon. Worked up loads using 4 different powders and 3 different bullets in under 2 hours but would only remember the one I stuck with if I didn’t have that 3 ring binder with me that day…in 20 steps and a little page flipping I could tell you every load and resulting velocity, I tried that day.

But no, it’s not necessary. Lots of people take things they have learned to the grave. The load manual you get your data from is an example of a “log book”…
I bought my present house from my parents in 1987. They bought it new in 1966. On the pantry door jamb is MY weight, height, and date along with that of my older sister & younger brother until we each left home for college. All the trim around those numbers has been painted I don’t know how many times over the years but the “kids’ log book” is original.
