keyboards kro is 3, most other nonautoconverts above 4k will use more then 4keys all the time, i will be starting to learn 7k as soon as i get a mechanical keyboard
I'd still play normal maps. Not often will more than 3 keys be pressed causing you to fail a map. Honestly, if you can press, practice and prepare for conversion onto real maps, then you'll be set for when you actually get a good keyboard. Even if you get bad scores, you can't blame it on yourself. As long as you try your best. Also, autoconverts are a terrible way of gaining skill as a player. The more you play normal maps the faster you will become a better player overall
