I'm certainly no expert and I do the same thing - fingers drifting in some cases or just being bad about judging how far to stretch for certain keys. I've particularly noticed this as I'm testing a new keyboard (TextBlade from waytools.com ). It is so much more compact that, while maintaining horizontal distance to a normal keyboard, you don't have to move nearly as far vertically. Old habits die hard.

This means, at first, I was missing keys constantly. But I adjusted to the point where I could sometimes get a fair number of letters right in a row though other times I was a mess. But I kept practicing. One particular thing I did was, once I got some basic consistency, was to notice what letters I was getting wrong. For example, I use a dvorak layout. That puts "I" where the G key is and K where the V key is and X where the B key is.

First thing I noticed was that I was often hitting X instead of K on dvorak layout. The K required that I pull the index finger down and to the left more than my hands naturally wanted to do with the TextBlade's ergonomic structure.

So, I created various sentences which focused on the letter "K" in a text file and I would periodically practice typing and retyping those sentences. Maybe something like this: Lick the lucky sock like a knife.

I know, the sentence makes no sense, but I was just putting in words I was missing and doing the best I could to make it into a readable sentence.

And I got better. But then I noticed something else. Most of my errors with K started happening if the K had an "I" right before it. Such as the word, "like". The reason became obvious. The "I" required my index finger to stretch a bit to the right followed by the need to pull it back more to the left for the K. This emphasized my problem. So I did new sentences that included words such as, "Like a likable child, he liked to mike the bike".

It let me really focus on a specific problem. Hasn't gone away, but it is much better. I've regularly gotten over 60 wpm and even over 70 with 97% or better accuracy. But I still get some bad streaks sometimes.

Writing down the words one makes mistakes with and then practicing those words, sounds like a very useful advice..... It'd be great if this website kept track of the words you make the most mistakes with!...

I think there are a couple levels they could do. One is just to focus on the specific letters you miss and then feed you more words with those letters. The other, giving you words with specific combinations of letters that make it more likely you'll make an error would be great, but more complicated. But even if they let the user create a list here of such words that they could draw on would be helpful. Or maybe a list, not of words, but of letter combinations. So, for me, I could enter "ik" and it would put more words in that have those two letters together such as: like, bike, trike.

I like keyhero.com as it is now, and love how it is free, and it is one of the few websites that listen to us users... but yes, you're right that might be useful... and dreaming is free too, lol.

When you finish a test, you are shown the words you messed up. It's up to you to write them down as you go and keep track of them.

Yes!. And also in the page source the errors are there, for anyone who can write a script that finds the words where mistakes were made, and save them to a file...
