Wouter I agree with most of what you are saying.

We'll probably give you the most efficient plate to get the lower rating; now that there is some direction in the SCHRS group, why did you not ask for this instead of asking for the rating to be lowered without providing the facts to back this up ? It would have saved a lot of typing if we (The SCHRS group) had been sent a request by the F16 association along the lines of

"as our class rules do not measure plates in the same way as the SCHRS rule, please use the most efficient rating point for our SCHRS rating, this being 0.14 (area) x 0.80 (length) (aspect ratio 4.57 dimensions 175 mm x 800 mm)
Kind regards, etc....."

Simplest solution is to adopt the most efficent plate for SCHRS for the F16. I will propose this to the group tonight, the only problem, is are you acting on your own opinion, or with some backing of the F16 association(s) ?

The slowest rating you can get for a F16 by only playing around with the plates is 1.04 :
