I'm having difficulties with your terminology. You've given special meanings to "distinction", "prospect", and "deal" that IMO don't bear any obvious relationship to their common usage ("event" makes more sense). Hence, I don't find those terms helpful in evoking the intended concepts. Seeing "A deal is a distinction over prospects" is roughly as useful to me as seeing "A flim is a fnord over grungas". In both case, I have to keep a cheat-sheet handy to understand what you mean, since I can't rely on an association between word and concept that I've already internalized. Maybe this is accepted terminology that I'm not aware of?
