Interesting tutorial.
While I probably wouldn't use it personally because I have my own way of doing walk cycles, this may work for people who are doing something specific to this style if it is their intent.
I could go into detail on why I wouldn't but at the same time, I really don't want to make this into a thing where I force feedback since that's not really your intent here to have that. I do like your moxie on helping others in spite of that.
