I absolutely agree with you that the case is in no way clear. However IIRC there is proof by combat reports and official squadron diaries (ORBs) that more than 16 squadrons used 100 octane before September 1940. Of course this doesn't mean that all squadrons used it. And this could also be caused by rotating the squadrons between the different groups.
