"One may have a subjective opinion as to whether the technique should be rewritten, but not as to what it actually says."
You must be new here.
We regularly get into arguments here about what the actual text in the reference books says.
Further, we even more frequently get into arguments about what the literally quoted passages mean.
For example, there's are those here who who still do not understand that the stated amounts of turn are measured between alignments, and that those alignments are of the feet. Neither the body alignment nor the direction of travel will necessarily match the stated foot alignment, or necessarily change when an amount of turn indicates a change of foot alignment.
