Good post.... Additional items that might help.....
Divide your Range card into sectors. For ex. A, B and C..... Efficient to index targets...
At your position note a magnetic back azimuth(label in degees and distance) to your RP.
Distances to TRPs can be lased, milled or scaled from a topo map.
In addition to noting your elevations its also a good idea to note your hold- offs for the
particular distances.
