Since no one has commented adversely on the above proposals I have removed much of the mathematical material to a new page for TM-Redfearn. I am working on two new pages, TM-flattening-series, TM-exact. I have also moved the Bowring material and discussion to its own page without any further comments on its value.
My justifications are two-fold. Firstly, with the two new sections mentioned above, and possible further sections for other variants, the TM page will grow into a rather large and messy article. Secondly, my sympathy with the general reader prompts the construction of a less mathematical page here. From this article she can gain a general survey and then go to more "advance" pages for technical details.
It is possible that the mathematics of the TM-sphere section should move. I favour keeping it because of the value of the figures to even non-mathematical readers. (ie the relation of the graticules and the introduction of convergence).
It would be good to have some feedback from other "watchers" on the actions I have taken (and possibly on the Bowring discussion). It would also be good to have some assistance with copy edits, link additions and checks of references etc. (on this page and the the TM-Redfearn page.
