Hi,
to cite from my original answer:
We did have some discussion on that patch too:
https://lists.open-mesh.org/pipermail/b.a.t.m.a.n/2014-June/012155.html
I wrote that patch because we had problems in commercial installations and dual radio access points, which were fixed by this patch (as described in the mail). I didn't hear any practical problems so far, you are the first one.
I guess its not easy to have a "one value fixes all problems" hop penalty, but its at least worth to discuss it - so thank you very much for your input.
Since we got this mail on the mailing list now, I'd like to hear opinions from other people and/or communities.
Thanks, Simon

Hello Simon,
we just updated our mesh, to the batman-adv-version 2014.4. Now your patch batman-adv: increase default hop penalty[1] is included.
Since we got very large mesh-networks, we have some troubles with your patch, which makes long (needed) pathes unusable, because they TQ drop to lower zero.
Else, we got some old and some new batman-adv versions, this change overloads the old nodes, because their TQ are better, and similiar links over new nodes got ignored.
Else I see no improvement overall, because the usual urban link-wide is about 30-50 meteres, and we got parts of the net where we need 4-5 hops to reach the last node. Your Patch seem to limit these pathes to something around 3 hops. So parts of our net are now offline, and the speed overall doesn't seem to be improved.
After these experience I like to ask you, if you mind reverting this patch again. Else we have to work around with resetting to 15 again on boot, which I think is not the prefered solution.
