Chemstation tailing factor determination

I was wondering if anyone could tell me if the peak height used for determining peak width can be adjusted in Chemstation. I am working with B.03.02 and need to get some alternate tailing factor values.

It appears to me that the calculation is fixed at a height of 5%, but I was hoping for some verification before I move on. Thank you for your time!

Every "width" parameter in reports is the peak width at half height. The only Tailing factor calculation uses the USP definition. There is a "symmetry" parameter, but it is based on statistical moments (I think) and does not generate a commonly useful number.

There are some additional values calculated in the Performance report styles, and they might help you.
