Colemak user, maybe a comparison: 2 weeks until I could "type" but it was frustrating as hell. About 1 month to 70wpm, which was the bare minimum where my thoughts would no longer outrun my fingers. After about 6 months I was back at 110-120wpm consistently, but ever since then I notice that I'm regaining little micro-skills I remember having, like hitting the right key upside down with my left hand while walking past the desk. So I suppose the learning never stops ;) About 7 years now.
