I have an Anvil Foundry without a pump. I mash in at 147F, then set the power level to 66% and set my temp to 162F. When the controller reads 162F, I stir my mash (which settles in somewhere in the low/mid 150's once it is mixed) and bump the temp up a few degrees. I keep repeating this process (heat, mix, bump temp) until it gets to about 180F on the contoller (low 170's actual mash temp), then I drain the grain basket. It's essentially a continuous ramp starting from a low beta rest up through mashout over about 70-80 minutes. I haven't noticed a significant difference in body or efficiency compared to my old usual 153F for 1 hour mash schedule, but the grains drain better at the warmer pull temp, and I'm closer to boil temps when my mash is done. This is certainly a "just because I can" methodology, but it works for me and makes good beer.
