Hi, 50 WPM is above average as you probably know, and all fingers/practice should definitely speed up your skills. Good sites posted by softeyes, BTW.
Ran across this article, either humorous or enlightening, though posted not to deviate from proper protocol, It also includes an interesting video:https://www.fastcompany.com/3056678/touch-typing-is-no-faster-than-pecking-with-a-few-fingers
One cardinal rule I always broke was to look at the keys (manuel/electric/virtual) instead of the screen or paper. Spellchecker today takes care of that, bottle/brush in cap White Out yesterday.
Best of luck in your endeavor.
