I got 261 CPM (52 WPM). I'm not writing the "proper" way where you use all ten of your fingers or whatever. Most of the time I use only the first two fingers of my hands + left thumb for space , rarely the ring fingers and almost never the pinkies. It's just a "natural" system that I (and probably most other people) have developed before I found out about the "proper" way.
Do you guys know what is the reason behind QWERTY layout? Type writers that were based on regular alphabet layout used to jam a lot because people were writing too fast and technology wasn't reliable enough. Manufacturer, in order to solve that issue invented layout that will slow down people which results in less broken type writers. Somehow this design became standard and carried over electronic keyboards.
We have recent communism vs capitalism discussion where we criticized communism. Guess what, basic principles of capitalism tend to produce crap and that crap sticks for centuries. Inferior tech? No problem as long it brings more profit...
Now that we have digital keyboards that don't jam, it would be far better to transition into the OG fast layout. People who are already used to QWERTY would probably remain with the old layout, but children should only work with the optimal layout (DVORAK?) so that future generations can abandon QWERT completely, probably wouldn't be that hard to accomplish.
Another "wrong" but widely accepted system is the decimal system. It was originally designed for dumb peasants and children (ten fingers - ten digits) because it's easy to learn. But duodecimal (base 12) is better because you can divide 12 by 2, 3, 4, 6, whereas you can only divide 10 by 2 and 5 (inb4 nerds with their smart definitions and shit). A quarter of 10 is 2.5 - not round, "ugly" number. A third of 10 is 3.(3) - even worse. A quarter and third of 12 are nice numbers.
Another thing that bugs me is rpm on car tachometers. Why would anyone choose revs per minute over revs per second? It's kind of counter-intuitive because car engines usually spin relatively super fast, so why would you need a "long, slow" unit like minute. For example, 6000 rpm is equal to 100 rps, and rps is much better because (1) it uses less digits (2) it immediately tells you how fast the engine is spinning, much easier to imagine. If your engine idles at 900 rpm, it doesn't really tell you a lot. But if you calculate it to 15 rps, you start to see that even when idling, car engines rev pretty fast. Same goes for rapid firing guns.
