So I would suggest a simple script to space short vertical lines along Michael source line, at these logarithmic distances.
The numbers would be placed above for one set ( say C), and below for the other set (say D)

Also to be placed would be secondary pips.
This link talks of them, but is not very understandable, and has no pictures.

Michaels script LineWeb will make short lines between two lines, so all that would be need to be modified is the log spacing...
Or a logarithmic "array"...
