Samples 0 => safe setting => hash everything
Samples 128 => fast setting => hash up to 1 KB
Samples 512 => medium setting => hash up to 4 KB
Since there's at least one game that requires 4096 samples, 4096 samples should be one option.
The idea behind using 2^x values as samples is that a higher samples number results in the same data hashed as with a lower number plus additional data being hashed. So that's a big NO on 2560 samples.
Anyways, i did plan on releasing a test build of Dolphin that tells you which samples number is the lowest you should use. That build will be really slow, and you'll have to play every major situation(main menu, battle, videos etc.) for it to work properly. But when that build tells you to use, let's say 16384 samples, you will want to set the game to use 16384 samples.
But this build will have to wait until it's been decided how to implement this:
https://github.com/dolphin-emu/dolphin/pull/2097
as it affects the setting that works best.
