One thing that comes to mind about Solver is that in a 6th order polynomial,
Solver may zero in on the wrong local minimum/maximum. Do you have a lot
of data points? Maybe you could smooth your curve with a 3 degree
polynomial, or perhaps run a cubic spline equation.

Solver will do it. Is there any way to automate Solver so that it works
like
a worksheet function?

the

(eg. derivative where slope = 0 indicates maximum)
