Man, that Canonet note says it all. I still keep a paper log for my own repairs (started in 2009, nowhere near 1,100 cameras though, maybe 300). The trick is writing the fix and not just the problem. "Shutter gum, cleaned" tells you what to do next time. If I just wrote "shutter stuck" I'd be lost two years later. I also jot the date and a one word note on how it came in (estate sale, flea market, grandpa's closet) because that tells you a lot about what you'll find inside. Apps are fine for tracking a customer's ticket, but nothing beats flipping through pages when you hit a weird one and remember you fixed the same thing in 2014.

The part people miss is that aim assist in split screen is often not two separate systems at all. Most engines run one camera or target logic pass for the whole game, so both players end up pulling from the same enemy list at the same time. That is why the drift feels random and awful instead of just weak, because the game is basically arguing with itself 60 times a second. I saw this bad in Halo 3 couch co-op back on the 360, and Gears of War had a version of it too where the snap would yank your view toward whatever your partner was already shooting. Turning it off fixes the fight, but it also means your aim is fully on you, so there is a trade. The weird fix some games use is locking aim assist to player one only, which is worse because now player two is just playing a harder game.
