Actually I think he can be quite consistent.
He said that blades, properly assessed to a height that is compatible with what you would have had biologically, do not give you an advantage over an able bodied athlete - which was obviously accepted by the powers that be.
On this occasion he was stating that he thought his opponent's legs were longer than a biological replacement, and this would give him an advantage.
He had complained in advance of the games, and made an error to raise it trackside.
However, I think it is brilliant in a way, because a lot of people were discussing an event that previously would have been in the shadows of off peak broadcasting - yet this was an upset worth of discussion.
Paralympics has come of age in certain sports ..... not rowing yet, but it may well be dragged up there.
