I think both you and AntonioLao are the two best mathematicians on the block.

We ( the 3 of us ) can even do a paper on the Idea, if you think it's worth the effort.

Best to all,

You're welcome, and thanks for the compliment! At the moment, I can't see how to progress your idea mathematically. I'll continue to have a think, and more of a read of it though, when time permits.
