I think this concept and method is rather universal. No matter what method you do you will still have to develop these same filters in relatively the same way. I guess I did mention a lot of f2l in here, but just replace that with whatever you do as your method. So for Roux this would be your 2x3x1 block pieces and for petrus this would be you 2x2x2 block pieces, I don't really know waterman so I don't know the equivalent.
For roux at least, This is not the method that should be followed. since there are MUCH more kinds of blocks that you can make than just the 6 crosses.
Not to mention forcing yourself to build shitty blocks when the end goal is to have more options.
