Hi Ramy:
Your issue about my data is a little besides the point I was making - but to answer your question I am in New England where I am a former SSA director and the Chief Pilot for the largest club. In Region 1 there are exactly zero club gliders (counting all clubs) with FLARM, zero tow planes with it, and only about 16-18 privately owned gliders that have it. Particularly considering that the club gliders are doing the most flights and hours - that's pretty poor penetration. I am not saying that is a good thing - and I am a FLARM supporter - but outside the competition scene it just has not penetrated.

My point however - was (and is) that if you can't get people to mandate use of an accident prevention device - how are you going to mandate a accident diagnostic device?
