Ok.. I see that if you simply leave the numbers in the formula alone,,, and
just change FW to a lower value then you are going to change something
else...... but to simply change the ratio ... ??.. actually  there is a real
change in the "weight" component of Whippen Radius.... which as I said last
would affect the WBW as a whole and could easily turn this into a negative
number. But doing so wont change the Ratio...

And besides... the Ratio isnt really changed anyways. 

Why do you say then that this is a neat,  (and illusionary) phenomenon ? I
mean.. of course SW can be counter balanced with less FW... because you have
substituted for FW... not changed R.

Scratching my head her a bit.

Hmmm.... I dont know about this analogy...grin... sounds more like confusing
Water Buffaloes with Argentian Whitzie Flies to me. :)
