Yeah, that is what it should be for R12. Your question is a valid one, just no way to answer it. That is another problem with these "so called" Drop in replacements for R12, they don't always work and cause more problems than they solve. At least if you are running one refrigerant you can come up with settting based on that one refrigerant. There are some mixes, that the chemicals homogenize and have one set of pressure/temps for the mix, and these mixes are given their own R number
My understanding of Duracool, is it has just enough R290 to move the refrigerant oil around the system with the R134a, which is the primary refrigerant and makes up most of the mix. Given that, I'd try a POA setting close to that of R134a, but if you have to go through all that, why not just run 100% R134a and be done with it?
