My pleasure. I forgot to mention that I rake through the old coals with a Big Green Egg ash tool to knock the ash down into the pan. Awesome tool for that, lifting the coal ring in the WSMs to shake the ash off, picking up the grate, scraping between the Grill Grate fins, moving pans and such on the grills, etc.
I noticed some talk of running lower temps to add some smoke flavor to the steak, which is great if that's what you are going for. I personally run the higher temps to avoid the smoke flavor that may come from a stray chunk left in the old coals, as I don't really care for too much smoke flavor on my steak, in addition to allowing a quicker time to get to sear temps later as previously mentioned.
No relation to the Charlie Lewis of the custom razors, the Charles Lewis that supplied prostitutes and smoked crack with DC Mayor Marion Barry, nor the Charles Lewis AKA "Mask" of Tapout fame, sorry.
