this one can't be ok: it's inconsistent

14.8 lies between 14 (outside) and 15 (inside); you say it means that 
all 15 qualify, and some part of 14 (outside) qualify

on the other side, 18.3 lies between 18 (inside) and 19 (outside) and it 
means that some part of 18 (inside) qualify and no 19 qualify.

the treatment of both sides is non-symetric
