Minimum Tape Length Freesize constraint

Could someone please direct me to documentation relating to what the "minimum tape length" and "tape width" constraints in the composite tab of the free-size optimization options does?

full path in hyperworks 2020.1: Analysis -> Optimization -> Free Size -> Composites

Or more specifically, is it required that any tow generated by these options an integer multiple of the minimum length?

It seems to be the case, given the step-wise outlines of the element thicknesses:

Is there a way to set the minimum length, but have the maximum length be a continuous value?

When were these options added? every tutorial I seem to find online does not feature these constraints.

Additionally, what do the offset options: "LOFF" and "WOFF", control in this same tape settings tab?

Thanks!
