Pace:
It has been interesting to observe the fruits of much fine-detailed thinking and discussion that has been going on amongst Cirrus/BRS manufacturers/owners/pilots - for over ten years now- making its way to you via PPRUNE, 007 and effectively COPA.
I admire that you have been able to absorb new points, evolve your point of view and share sensible counter-points in the discussion (eg 30 knot surface winds) and grow your (and wider) appreciation for the safety value, subtleties and pitfalls presented by the existence of BRS through discussion.
You have an appetite to discuss even further detail, but I think you dissuade discussion of finer detail by simultaneously persisting with highly subjective propositions. E.g. "He allayed his fears with the thought that if the worst happened and the weather was down when he got there and he really could not cope he would not die he had the chute."
If there are those who regard a chute pull as a no-consequences get out jail free 'easy out' reason to go flying where/when they should not their lack judgement (and imagination) is a very big risk to them, period. Perhaps any population has a small Darwinian element, whose behaviors (actual or perceived) tend to be given greater prominence in discussion than those of the vast majority who would gain value from discussion of points that they themselves can consider/control/influence.
Finer discussion on BRS would largely be about exploring more of the many grey areas in more depth than a quest for "Black and White" answers/POH content. Factors present in a real-life pull/no-pull circumstance are so many and varied and preclude the concrete 'circumstance proof' guidance that you seek.
Identifying, considering and incorporating (or not) those factors into "SOPS" is where each individual BRS pilot makes his own choice - even as to whether or not he/she chooses to explore/discuss them - and is where discussion threads like these can, I believe, contribute to participants safety (excepting another very small part of the population whose judgement and performance is so consistently high that they will, with no need of a BRS, either safely handle any circumstance which fate might send their way, or accept that fate if not able to effect a good outcome for whatever reason).
