Maybe I am missing something, but on resizing a bode plot then between 10^0 and 10^1 for example
a 5.0 * 10^0 is shown. Moreover a subscale between 10^0, the 5 and 5 and the 10^1.
I am acustomed to a linear scale on the exponent so the devision lines represent 2,3,…,8,9.
But this subscale around 5.0 makes no sense to me. Is it correct and how is it usefull ?
