I viewed this video a good while ago the method and info seem to work in the situation/presentation. The philosophy of usage seems sound for the most part. This drummer/percussionist is obviously skilled and experienced. Kudos to that, seriously.
I however think that the method leaves out several variables:
- It assumes that the drums/drum shells are in the round with good bearing edges and sound good
- It assumes the proper head combination for user kit "x" playing scenario has been chosen and are quality manufactured - as all drum heads are not
- It assumes that the drum kit shells are in a reasonably proper tonal interval/separation and that the person tuning can hear and replicate this in their tuning procedure - as some drummer do not have a melodic ear
I respect the info in the video clip and the presenters skill set. I however have found over the years that tuning is an artful skill and not everyone whom plays well can actually tune drums well- even professional players and instructors. If this were not true most producers would allow the hired drummers to tune the kit for it's recording... or even choose the drums to be used and that simply is not the case in most mainstream professional studios.
This does not mean that this method is not a valid or good/great option/method to use. It is simply in my opinon that in tuning/learning to tune one has to respect the "game" and truely learn HOW-TO well... not just the simplest/easy way which may not be the best sound production.
