This was one of the first programs I wrote in Basic in 1975. I got down to 2-3 secs. I used "fingerdragging", so you do CDE, FGH, JKL and ÅÄÖ in one movement.
Haha yea that is something that I have been doing. I notice that I have major spurts in some because i can like drag a finger across a couple keys and get them ready for the next.
