I really only do it a few times (until it feels nice and silky). But I think boars tend to dry up and become stiff again without regular use. I don't know that they ever become fully broken in, just conditioned for use with regular use if that makes sense.I can see doing it a few times, but not like our fathers and grandfathers did in perpetuity. For myself, I have never bothered with any means of trying to break in a brush faster. It'll get there eventually. I'm in no particular hurry. Glad it works for you though and you're satisfied with the results!
