possibly serious bug....need someone from HP...

[webmasterpdx]

in fact, what I was doing to keep the calculation in the continuous part of the curve was to use x-deltaX, where deltaX I varied from 0.001 to 0.5.....seems to work as long as I use a value in that range.

However, I still don't know how it achieved it's result as stated in my previous post....and it doesn't make much sense.
