Hello Brian,

don't give up just yet.

I have been doing quite a bit of work lately on analysing systems with a view to determining if they are "good" or "bad", and also to determine whether the current short term trend is just a phase or an indicator of much worse....

If you'd like to email me offlist I'll go into further detail for you if you like.

Cheers,
Chris.
