This makes a lot of sense to me. Looking back at this with hindsight
most of the problems I have had with the swirls were caused by rapid
heating of the glop, and pouring at the high temperature. Whenever I
have allowed a lot of time for gradual heating, and just a bit of
cool down before pouring, the swirl pattern problem has been minimal.
