Yep, there's at least high variability. Especially if the things it could be taken to mean are things people generally have similar credence for.
And, nods, this was partly a test of trying to disambiguate a claim, and I found it harder than expected / think I did not do very well. Maybe just words would have been better rather than numbers, and more of them. Or maybe doing a simple version and having other people see where it was ambiguous rather than trying to clarify in a vacuum is easier?
