You undoubtedly make mistakes in the learning process, so this is actually a bad idea for learning.
This would scare you into looking at the keyboard, thus preventing you from actually learning. I type at ~100WPM (which is higher than average but im sure some of you are faster ;) ). I've learn new keyboard layouts (split, colemak), and the best way to learn is to not look at keyboard, and try to remember where the keys are (and constantly trying to type as fast possible [using muscle memory instead of memory], which makes even more mistakes).
While you are correct on not looking at keyboard, trying to type as fast as possible is wrong way to learn it.
Just as with any instrument, you don't want to learn to play it as fast as possible, but rather first you learn it slow and correct and only then ramp up speed but only as long as that speed still feels almost effortless.
I have first learned QWERTY at school (yea, fun school...) but learned it the way you presented. Then couple of years later I decided to learn typing properly and re-learned with Dvorak. I used metronome initially and dropped it after couple of days.
I’ve heard this advice before but I find it really demotivating. I recently realized that I type with all 5 fingers on my left hand but hit 90% of the keys with my index finger on the right. I’m fast mind you - 90-100wpm blind as well. But for any prolonged stretches (10 minute+) it starts to hurt.
So a while back I started doing 10 minute a day typing exercises with Typing Academy to train my right hand. Whenever I did it blind it was just mistake after mistake after mistake. I felt so incapable. But when I started looking down I was able to correct myself and still use the right technique. Much better. I was slow. But slowly learning without frustration.
I guess my point is: crawl before you walk, walk before you run. The frustration made me quit, and that’s always worse than looking down and learning.
For me the issue solved itself when I started using my first
columnar staggered ergo keyboard, meaning instead of having the
key rows slightly misaligned for historical reasons it has a
different height for each column of keys to accomodate the
different finger lengths.
Doesn't sound like such a drastic change, but within minutes it
will teach the user in what ways they've been typing incorrectly
all along - and in what ways the standard keyboard layouts
actually promote incorrect typing. It takes some time to get up
to speed again, but nowadays I type using all fingers evenly
~95% of the time, simply because in contrast to the
off-the-shelf design it makes correct typing far more
comfortable while requiring quite some finger gymnastics to pull
it off any other way.
Of course due to the different design it's not quite as
flexible, for example it's not great for gaming and mainly
shines when the mouse is used sparingly. But as I mainly work
with text it's been a great experience for me.
