I can't offer you much on the batt life using your above formula. My style is very long lung hits, and I vape all day and night anytime I want to. So batts and joose come and go easily around here, why I have such large stockpiles of both and chargers that will do 8 batts at a time. I average 30ml of joose used per 24 hour period. So there is no way any batt will get me through all day let alone night too unless I am rotating several Reos at the same time. I have 6 14500 Reos that were being used exclusively for a while, 3, 4, 5 or 6 at a time. Never paid much attention to how many batts it took, but keeping the little bottles from running dry on joose was a constant chore.
Maybe if one of the ladies chimes in that uses nothing but the 14500 Reos, or others that use them exclusively sometimes did they can give you more exacting info.
I wouldn't negate the other atty's for a MIni 1.0 just because they have slip on caps. My choice of the 4 in order would be Chalice, RM3, Hornet then RM2. I only put the RM2 last because of it's weight and bulk on a small lightweight Mini Reo.
