You're right, I didn't think this through.

Reducing the step size has the disadvantage of making the measurement
harder on the network, unless we simultaneously reduce the # of ping
packets sent.

In fact, we get the very same behaviour by setting pings = 1 and step =
15, so there's really not much point having a new variable for it
