I watched and listened to this yesterday. Very interesting to hear the topics and opinions. I do agree that each brewer needs to look at some of these suggestions and see what works best for their brewing setup and process. What works for one person, may not for another or what is an issue for one person may not be one for another.
I have only done step mashes on a few beers and one decoction mash in my 11 years of brewing. I really did not see much benefit on my system to make it worth the time. I may do it again, but it's not a regular practice of mine. If this works and helps others with their beers, great.
Thanks for posting the video and thanks to Denny, Gordon and John for the insight.
