I always do
"what simply works".
Sometimes I do
something, and days/weeks/months review it and see that it could be better/or
is causing a problem, so I refactor. I dont think there is one perfect way, it
also depends on the project as well sometimes.

Cairngorm... Where should this go?
Thanks for your suggestion Dimitrios...
I had thought of that too but in the MVC architecture, doesn't that
put logic into the view? My impression of the architecture is that you
should be able to create a different view over the same model without
duplicating code. I mean, I don't want to have another view and am
more or less positive I never will but looking at it from a purist's
point of view is this the 'correct' way to do it?
I suppose if the rules that you validate against are kept within the
model ie. min and max allowable responses for the current question in
my case then your suggestion would be the 'correct' way of doing it.
I think I will go with your suggestion but I would be interested to
hear if you, or anyone else had any further opinions...
Thanks again...
