Ever look at which specific pictures it's getting wrong? I had a model that was great at obvious stuff but failed hard on anything with weird lighting or odd angles. Started tracking error types instead of just the overall score, and that showed me where to add more training data. Like @fox.david said, that last bit is what kills you. My fix was to go find a bunch of examples of the exact things it messed up and retrain on those.

Totally agree with that call. The peace of mind alone makes the copper upgrade smart, since those old aluminum branch connections are a known weak spot. It just future-proofs the whole panel, you know? Dealing with a potential failure later would cost way more than the material difference now. Makes the whole system more solid for whatever gets added down the line.

We had a moving job where a fancy treadmill wouldn't fit through the door, and the client was ready to return it. Turns out you just pop off two plastic end caps to shorten the frame. Their face was priceless when we showed them the tiny parts, kind of like @benc53's point about paying for the know-how. It's wild how often the biggest headache has the smallest fix.

Yeah the duct tape thing, I read somewhere that if you're using more tape than wood you're basically just making a mummy.

Oh man, that is the realest advice. I did that for two months and was shocked by how much I spent on dumb stuff like snacks at the gas station. It sucks to write it all down but you can't argue with the numbers. I use a free app now just to keep myself honest.
