I think you are lucky in selecting your check points if you are checking and getting dead nuts values.
That card has 12 bits of resolution. (Note that even though the value in the PLC goes up to 32760, the least significant 3 bits are always 0 so they don't count for resolution).
But the full range of that card goes to 10.5 Volts so you have:
(2^12 steps) / 10.5 Volts = 390.0952 steps/volt
Since you are only using 0-10V your full scale steps are:
10 Volts * 390.0952 (steps /volt) = 3901 steps
Essentially your resolution over 36000 feet is
36000 ft. / 3901 steps = 9.23 ft./step
