Depends on the configuration of olsrd... but if MPRs are activated you
might be right.

Of course every MPR transmission is a broadcast, so you still have
multiple chances to receive a package in a dense network

Difficult to say. Most times they will be slightly wrong. But the
routing tables are only used to determine the next hop, so errors far
away from the target should not be critical (that's the idea behind
fisheye routing).
