I've been trying to get used to Lojban's indicators, and have at least
a general feeling for many of them. But I'm finding that Lojban's
standard evidentials don't quite seem to cover a way I'd like to
express myself.

To try to summarize: in a book dealing with statistics and probability
and Bayes Theory, E.T. Jaynes has shown how it can be useful to deal
with probability logarithmically rather than linearly; and with a bit
of simplification, applying this to Yudkowsky's theories of everyday
rationality, it would be useful to have an evidential that could
assign an integer's value as the strength of the speaker's belief in
what's being said. For some rough English examples: "(Bayes 6) It's
going to rain today" meaning I believe there's an 80% of rain; or
"I'll be taking the bus (Bayes -20) home", meaning I think there's
only a 1% chance it's the bus I'll be going home in. (A bit of further
explanation on these numbers is at
http://www.orionsarm.com/eg-article/4d5bf17b86585 .)

If nothing else, I'd like to be able to use a construction like this
in some SF stories with a character who likes Lojban, even if this
can't be part of 'real' Lojban. So at the very least, could anybody
here recommend some way to construct even a fake evidential to do
this, which won't have too many unfortunate collisions with real
Lojban?

For example, I'm thinking that a currently-unused set of letters in
the indicator/UI pattern could be appropriated for the task (perhaps
something close to the existing "la'a"), followed by the number,
optionally followed by "do'u" if needed to keep the numbers from
getting mixed up with the rest of the sentence; but I'm sure there's
some reason why that's infeasible.
