Better order a few and be ready to cut them. I have a handful and still haven't found a good combo.

I ordered one and used the recommended chart. My vacuum at operating temp is about -16 in/hg, so I ordered it with the -9psi spring (-14 to -17 in/hg)

I think you should be safe if you follow the chart.
