Dear Tony,

Wow.  That does indeed seem to me to be a big red India rubber ball!!!
Rapid fit, and the ominous warnings go away.

I tried it with the real data --- likewise rapid fit and no warnings.
Haven't done any thorough checking of results yet, but it sure looks 
like progress to me.

Thanks hugely!
