Good to see an article backing me up! Just a couple of points: I never rub out "excess" shoots and I don't get an over-abundance of tiddlers. Damaging a tuber in that way just before planing doesn't seem such a good idea to me. The other thing is that spuds will chit in the bag if you buy them a good while before planting. If they do that it's best to then spread them out in trays.
