+// LOG:
+// late Jan 2020, got Ohkeycaps Dactyl Manuform 5x6
+// https://play.typeracer.com shows about 75-80wpm (en) or ~400cpm (de) on my classic keeb.
+// Never did proper touch typing, basically didn't use ring finger much, mostly index/middle and pinky (only to hold down modifiers, really).
+// Feb 2020, switching to Colemak DH after 30 years of Qwerty, uh oh...
+// mid Feb, 20wpm/87% on monkeytype.com (no punct, numbers)
+// early March, 28wpm/90% on MT (plus punct./numbers from here on); 25wpm on typeracer
+// early April, 35wpm/92% on MT; 41wpm on typeracer
+// early May, 45wpm/96% on MT; 46wpm on typeracer; my qwerty is deteriorating, I need to look at the keys more and more o_O
+// early June, 49wpm/95% on MT (sigh ...); 50wpm on typeracer;
+// early July, 50wpm/96% on MT (...); 52wpm/96% on typeracer;
+// early August, 55wpm/96% on MT; 55wpm/98% on typeracer;
+// early September, 57wpm/97% on MT; 58wpm/97% on typeracer;
+// early October, 59wpm/96% on MT; 61wpm/97% on typeracer;
+// November, 56wpm/97% on MT; 62wpm/98% on typeracer;
+// December, 62wpm/96% on MT; 66wpm/98% on typeracer;
+// January, 61wpm/97% on MT; 65wpm/98% on typeracer;
+// February, 64wpm/97% on MT; 67wpm/98% on typeracer; my qwerty on the laptop is still fine, but I miss my shortcuts badly.
+//
+// So that's one year on Colemak. Was it worth the switch? Probably not, though
+// I also had to first learn proper technique, but that was actually swift, as
+// the keyboard nicely forces that on you. I really like home row mods though,
+// they are so comfy. Need to rethink my combos some more, still.
