No Ed, not on acid nor having a laugh. Only one S1 flew advanced this year and that was yours. Not a very standard airframe or engine I think you will agree.
Of course a standard S1S can be flown at advanced level and I had been intending to do so myself last year until my plans were changed for me. However most people at that level move out of Pitts into monoplanes. That was the the basis of my remark.
At standard and intermediate levels there is more to be gained from the flat bottom wing than from the round wing. That is what I mean.
