So, I browsed around a little. And knowing that Workman has a bit of a standing and is implemented both here and there, I chanced upon its main page – the Workman layout blog.
Here, its author manages to say the following:
Workman has an SFU of 2.185% which means that for every 46 keystrokes, one of your 8 fingers does one double combo. Compare that to QWERTY which is at every 20 keystrokes. Colemak is at every 58 keystrokes. Workman, on average, has a higher SFU than Colemak… at +1%. Some people misunderstand and think that this somehow shows increased effort or discomfort. It doesn’t. Effort is the same, because no matter what, you’re still pressing the same number of keys. Comfort shouldn’t be a problem as long as the key is in a comfortable spot. The only thing that SFU might potentially and theoretically affect is speed because typing two letters with different fingers is a little faster than typing them with the same finger.
This fills me with wonder and horror. Ostensibly, Mr Bucao has never played a musical instrument. But it looks to me as if he has never typed properly either, to be able to say something like this?!
It should be very obvious that drumming your fingers one after the other is a lot more comfortable (and faster) than repeatedly drumming with one finger.
Why, then, does this layout get any attention still? I wonder what happened. Expert advertising?
Good thing that stevep99 fixed the DH issue using Colemak, then. No need for Mr. Workman and his weird typing attitudes any more! :-o
