Correct. The "." means all moves were searched, and the search for this depth is
complete.

>11--        // PV changed working on 11 -- PV length was 10?

This depends a bit on runtime parameters. With default (faillow_early 0) this
means that the best move at iteration 10 failed low at iteration 11.

11++ would mean, that the move fails high (with the aspiration search window,
not with zero window, see below)

>11t         // PV changed working on 11 -- PV length was 11?

This means, that this is a "true" PV, that was searched to end, and was inside
the search window.

>11t+        // ?

The first move in the PV failed high in zero window search.

A following "11t-" would mean, that this fail high could not be confirmed with a
wider window. Well - a problem, I think we all don't like, but which happens

>11.         // full search depth 11 complete?

Yep
