Yes, the logic is simple, it is simply an axiom of "garbage in, garbage out" which literally means you must go through the instructions for a particular bounty and access the various campaigns alongside the stakes therein.

Go for the ones with higher stakes and exert in much strength, vigor to make your job unique and spectacular and you stand a chance of earning bigger for a job well done.

what ever effort you exert, is proportional to the result you get, so work hard as a bounty hunter and get a big catch for yourself.
