@Michael

Thanks for the explanation and the tips about increasing the spans for smoother results. Moving the point sounds like it would be a useful addition to the tool.

@Mauro

Cheers, looks like a really nice solution and final result. I have noted that Michael has significantly improved Network over the 1 & 2 versions of MoI.

Just one question. How do you know when to use Lighter for Network or Custom ?
When using Network->custom how do you know what figures to type in the input box ?

Thanks for the tips about increasing span for smoother results. While it didn't work in this instance the tip may help when I use it for other things.
