Many thanks @inquis for asking the question. I realized that I was using very different safety factors depending on flow.
I built a simple spreadsheet to calculate the safety factor for a given turnaround pressure (column C) or calculate the turnaround pressure for a desired safety factor (column D). Input cells are in yellow, output in orange. You can use either metric or imperial units as long as you stay consistent throughout.
