However, ignoring it will just move the problem forward to another bug report, will it not? Hysteresis is a slam dunk here. In addition, since the low-pressure state is bound to be transitional (soon to be followed by a real num_fingers==1 package), simply skipping such packages might be a better option. > > Why not introduce hysteresis for all fingers here?
