Given how lopsided the sales are to the lower end at 8.55-9.33 ref, I'd have excluded everything at and above the 9.66-ref tail. But 9.77 ref as the ceiling gets a very hard pass with 2 sales instead of just 1.
Taking 8.55-9.77 ref for now, unless price mods favor the more statistical exclusion, in which case I'll resuggest based on that.
