I was surfing questions this am (Damm insomnia) and someone had a link to an easy to understand brewing how to manual that was very well written and covers much. The section on mashing stated that circulating the wert shouldn't happen until after its through mashing. I have for a couple of years started circulating, herms, about 20 mins into mashing to do a step mash or just keep at the target temp and be ready to boil as soon as it's through mashing. What say you, the Brew Masters of this wonderful site. Always learning to be done!! Thanks Damm spel chacker, had to edit twice!!
