Dave, why not?
My thoughts too Rob.
Whilst one would clearly not run any engine for long periods at WOT unnecessarily, - and without being loaded particularly, I would consider WOT testing essential, as part of the diagnosis and process of elimination. I would also, suggest that most subtle fuel flow, air flow and air to fuel line leak problems do not displayed well, until under load and demanding higher/highest power output / fuel air use. (been there).
