I touch typed qwerty for about 20 years using really bad technique(full left hand two fingers on right that roamed). When I got my first split keyboard I switched to Colemak and went through a bunch of touch typing tutorials to teach myself proper form. Without switching layouts I don't think I could have forced myself to start using proper form in qwerty.

Same as you. I switched to ColemakDH for a while and noticed that it improved my Qwerty typing speed.
