Several years back when Middo was running the show, those aircraft would have never made it on there in the first place. There is a clear formulae (or at least there was) that determined if an aircraft would "fit" the 2-seater rule. Quite obviously nobody of recent time followed this rule. We had a situation back then with an aircraft where with full fuel the passenger would have had to be <50kg and it was rejected. The resolution at the time was to change the prop (to a lighter) , or reduce the weight of the aircraft somehow by only a couple of KG's and then it was good to go.
