HZ/4 == 250ms works except for HZ=122 (~246ms) and HZ=50 (~240ms). I don't
know how you think it is possible to find a constant around 250ms which
works for all HZ values. The problem gets even minor if we do
(HZ<<idx)/4 instead of (HZ/4)<<idx in which the inaccuracy only happens
if idx is 0, i.e. interval == -2.
