Is anything wrong with these?
Most likely not, but someone on the mailing list with deeper knowledge on B.A.T.M.A.N. V's echo location protocol could actually check whether non- symmetric settings on different nodes could create problems or not. Or if having both ELP and OGM2 interval set to the same value could have negative side effects.

Btw. it looks to me like B.A.T.M.A.N. V is a really bad choice for your setup. All links have the throughput value 1.0 Mbit/s. This sounds to me like the wifi driver doesn't provide the required expected_throughput. And so you have a REALLY, REALLY, REALLY bad metric when you are using 1.0 everywhere. So if you want to continue experimenting with B.A.T.M.A.N. V then you should try to get this fixed in your wifi driver or just switch to B.A.T.M.A.N. IV with increased multicast rate.
Are there any docs that talk about what B.A.T.M.A.N. V vs B.A.T.M.A.N. IV is good for? The decision to upgrade was made before I got here, I'm not sure anyone understood that IV would still be supported/expected to be used.
Lots of stuff I don't understand here, looks like loopback is very busy?
Not sure what you mean here with loopback. I will just leave the whole output here in case somebody else on the mailing list wants to figure it out.
