I wasn't coming down on you. I think all our own systems start as an amalgamation.
Personally, I am fascinated by COTH/L but don't use it. It's not mine. I've seen it fail, and I've got plenty of my own things that fail! Plus, I don't swap in and out that much during the day, so it's not something I use, really. But that's me. I can definitely see how it can help entries and exits.
