How it works
Slow and right beats fast and fixing. A mistake costs more than a slow key.
To fix one slip you stop, go back, erase it and type it again. That is a lot of extra steps for one little slip.
Find a pace that is slow and steady. Press one key, then the next, in an even beat, with your eyes on the screen.
Let each finger land before the next. Speed is not something to chase.
