/.../ My memory of it is entirely muscle memory, as was advised by the little book I learned it from /.../
I cannot but agree. We now have three methods that can rely mainly or entirely on "muscle memory": The Wave, mine and now this last one. The advantage is that memorizing the pattern is not needed to tie the knot correctly, but only remembering the way of tying it. It is useful in the process of learning to check the pattern, but in the actual situation of tying, you haven't buried it into your body's memory if you need to check the pattern. The correct tying method, whichever you use, results in the correct pattern, which is only an aid when learning to tie the knot. Once the method is learned and well rehearsed, you may as well forget the pattern, still being able to tie the knot anyway.
I think too much emphasize has been put on the pattern, to such a degree, that many people don't even know how to work the knot into its final shape, and several knot books also omit this crucial part of the tying process. The finished knot is something completely different than the pattern that is always emphasized. Contrary to popular belief, it is not a knot prone to capsize; its "capsizing" is the final step in its making, it "capsizes" easily and shall do so, to attain it's final stable form, from which it will not, and cannot, capsize.
And as stated. verifying the knot is not easy, if you have to, it may be simpler to untie it and tie it again the way you know is correct. This might be regarded as a drawback, but on the other hand, there are also other reliable knots that are equally difficult to verify just by looking at them.
