POM material

Hello, first of all I really love it! I’ve been playing around with it, and I’m impressed.
I have a little question about the “offset only” function. In my case I have two normal maps (main with height map, and second just a detail with more tiling) and I wish I could make them bumped with that height map.
I would love to understand more in detail what should I actually do since the tip in description is quite confusing for me, and can’t figure it out. From description that looks exactly what I’m aiming for:

“Use when you want to use t he offsets with textures that need a different tiling factor than the heightmap.
You need to multiply the offset by the tiling ratio between the surfaces. Ie, if the Heightmap had a tiling of 1, and a second overlay detail texture had a tiling factor of 8, you need to multiply Offset value by 8 before adding it to the UVs of the detail texture.”

I would really appreciate any more help, if not best would be some illustration. Thanks in advance.
