So, if we are talking probability, then the probability of walking away from a chute pull within limits, with a repairable aircraft it is PROB 99. Walking away from an off airport landing with the same outcome? I'd say PROB 50? I know which option I'd take.
If you want to base such a decision on completely made up numbers, then be my guest. Just remember that you have no second chance should the BRS malfunction and only partially deploy, unless you also carry a bailout rig.
