Thanks jcl. Yes, I understand all the general qualifications. But that's not the same as specific confirmation that performance is in line with others' experiences and not "gone off the rails" due to some other problem. Thanks for that confirmation.

I just hope Z3 will quickly stop feeding my ulcers - they're bad enough already...

FYI, I actually consider this as one of the benefits of the Z's in contrast to my own strategies which exist in a vacuum. With the Z's, it's possible to compare and (hopefully) reduce the possibility of failure due to other issues...

Thanks.
