a n e t r o are the top six in order of sequence and Colemak has a 3.5 same finger rate.

Same finger rate is how often the same finger is used twice in a row, it's best to keep it under 4%. But it's not necessarily bad by itself. If most of the same finger combinations are on the index and middle fingers (E-D on qwerty) and adjacent then it's not bad. But if the same finger combinations jump the home row (Y-period on Colmak) or occur an the pinky then and middle fingers it can a pain in the tendons.

By the by, aside from practicing on TyperA.tk I don't type Swedish. The information came from analyzing "Verner Von Heidenstam" by Folkungaträdet with a program written by Michael Capewell to give letter frequencies. And a java applet by Jon A. Maxwell that gives letter statistics about how a keyboard handles a text.

Typing Swedish on a vanilla colemak layout is not that nice since then extra vowels å,ä,ö are all on the top row (q,w and p keys (in qwerty layout)). Although, while I have not done so myself yet I was planning to swap the opt/alt state of the q,w and p keys with the home row (probably the same columns, but I do not know yet), in order to make the keys easier to reach. At the moment, when I write Swedish with Colemak, I transliterate the vowels to a, a and o respectively, just because I do not like moving my pinkies when pressing alt. I will not replace any of the normal state keys, since I am a programmer and use punctuation symbols more than the vowels.

I am considering making a Colemak derived layout optimised for programmers who write Germanic languages (or at least Swedish and German since they share two vowels, for Norwegian and Danish it is probably best to have the same layout but swap ä with æ, and ö with ø).
