Mason's/BruceZ's ROR formula.

Does anyone have a derivation of these formulae? I'm just curious as to how they were worked out. Mason/BruceZ?

Here is a derivation (http://forumserver.twoplustwo.com/showthreaded.php?Cat=&Number=683150&page=0&view=ex panded&sb=5&o=14&fpart=2#Post682045683150) of the correct formula. Here is a discussion (http://archiveserver.twoplustwo.com/showflat.php?Cat=&Number=207100&page=&view=&sb=5&o =&fpart=all&vc=1) of how it is different from Mason's formula.
