The badness heuristic has since been rewritten since the introduction of this tunable such that its meaning is deprecated. The value was implemented as a bitshift on a score generated by the badness() function that did not have any precise units of measure. With the rewrite, the score is given as a proportion of available memory to the task allocating pages, so using a bitshift which grows the score exponentially is, thus, impossible to tune with fine granularity. A much more powerful interface, /proc/<pid>/oom_score_adj, was introduced with the oom killer rewrite that allows users to increase or decrease the badness() score linearly. This interface will replace /proc/<pid>/oom_adj. A warning will be emitted to the kernel log if an application uses this deprecated interface. After it is printed once, future warnings will be suppressed until the kernel is rebooted.
