That isn't random amounts. There are 50 standard CTCSS tones and the up/down arrows scroll through them.
It also has nothing to do with the VFO frequency tuning steps of 2.5, 5.0, 12.5 KHz.

The problem is the ctcss codes on the Baofeng seem to increase by random amounts ranging from 2.3 to 3.7 on the codes I have checked so far.
