The first stupid hack question would be to increase the chain tension by removing a link. Or two. It doesn't fix the problem.
(you DO carry carry a chain-splitter tool, air pump, patch kit, tools, just checking)
And there is a way to measure derailleur spring back-tension of course.
The next question would be check lateral run-out of gears. Warped disks.
They can tweek L/R but they should not. Not compared to knees.
Like a saw blade.
