Not sure the pension calculator is intelligent enough to give you the correct answer in the circumstances that you describe. If you read the AP (haven't got the reference handy, sorry) it clearly states that PA pension credits only kick in if you complete the complete the 5 yr RoS associated with PA.
It is my understanding that if you PVR and leave before the RoS is fulfilled your pension will be (slightly?) worse than if you had left at your 38/16 point.
If you want my advice based on my experience, don't even bother asking PSF. Read the books yourself, and join the FPS so you can dip into their expertise.
