Is this what, you are looking for. I am confused on your ? But look over it
I have a lot of Data on this subject.
This site has a lot of good info plus this. Go Thru Geodesy also.
Look under Corrections

Here is some good reading.
Here from NOAA , I sent these 2 to Raymond Kinglsy on one of his Discussion.
But NOAA has a lot more on this subject at there site.
Did I forget to tell you I added one on Geoid and MSL, there is also some more info on it.In the others. Thanks for the programs again i never seen these P to R or the R to P. I like it,very short, i like that. that is why i use mine so much. I will try them in some programs.
Some of this might help.
From PS reference handbook:
Correction = −0.005288 sin2φ h Δφ arc1′
where: φ = Latitude at starting point h = Datum elevation in meters or feet at starting point Δφ = Change in latitude in minutes between the two points (+ in the direction of increasing latitude or towards the pole)
h ≈ H + N
where: h = Ellipsoid height N = Geiod undulation H = Orthometric height
Hi friend look this link...
you can find it at the end of your total station field user book.
at list at the leica´s field user book.
