Hit 500 welds logged and it flipped my whole system

I started keeping a weld log back in March, just a spiral notebook with date, joint type, and rod. Last week I hit 500 welds, which sounded like a nice round number but nothing huge. Then I looked back and saw my reject rate dropped from like 1 in 8 to 1 in 20 over those same 500. That changed my mind about tracking every little job, I used to think it was just extra paperwork. Seeing the actual numbers made me realize the slow days with fit-up issues were teaching me more than the fast ones. Has anyone else kept a log for a while and noticed a pattern like that? I'm curious if I should add filler metal type or just keep it simple.

My log is half notebook, half confession booth at this point. The reject rate drop is real but so is the ego hit when I flip back and see three failed overheads in a row from last April, scribbled next to "ran out of rod and got angry." Adding filler metal type might be overkill unless you're chasing porosity monsters, but I'd say track your rod brand too, since switching once showed me one brand liked to act up on verticals. Slow days did teach me more too, mostly about how long I can stare at a fit-up gap before admitting I need to shim it.
