In the choice between Asset and Colemak, I guess what it comes down to is how much Qwerty similarity is desired. Asset keeps 12 letters while Colemak keeps 10; and in total, my Nov. 13 redesign also keeps 20/26 letters on the same finger, whereas Colemak only keeps 15/26. Unfortunately, how important it is to keep keys on the same finger is purely a matter of opinion, because it would probably take a quite expensive study to tell for sure.
Now, Colemak and Asset have many similarities, the only major differences I can see being that (1) Asset is more similar to Qwerty, (2) Asset's Y key could be better placed, and (3) Asset has higher same-finger typing.
Colemak's designer, Shai Colemak says that "Asset has 100% more same-finger ratio compared Colemak." That could be true (evidence?), but I tried a corpus of several books at http://colemak.com/Compare and found that Colemak usually has under 2% same-finger typing, which implies under 4% for Asset. Now, if we assume digraphs typed with the same finger take twice as long to type as digraphs on different fingers (actually I think it's less than twice), then we would conclude that a Colemak typist could potentially type about 2% faster than an Asset typist.
So that's the trade-off. More similarity to Qwerty or 2% more speed. I guess we'll let the community decide. Mind you, Colemak has more followers so the conclusion is probably foregone. Anyway, I guess I should resubmit the new Asset…
It would be kind of nice if Shai and I could come to a compromise. For example, on Colemak's home row you see ARST:
If he switched R and S then S would be back in its Qwerty position, and the Ctrl+S (Save) shortcut would be preserved. My digraph data indicates that if R and S were switched, the amount of same-finger typing would increase by 0.22% (e.g. 1.92% instead of 1.70%), so one might expect typists that are 0.2% slower—no big deal, IMO. I guess he wouldn't think it worthwhile, since he has declared the layout "stable", but as I said on the forum… if he switches them, I'll drop out of the competition and replace my Asset page with a page that praises Colemak :)
