Heres the answer to the ST that should be SP from the guy that programmed the

That was a miss-abbreviation that should have been SP, (it was corrected on
some timing slips, towards the end of the week). SP stands for Station
Pressure, which means un-corrected barometric pressure. Barometers measure
air pressure, but since air pressure also varies by altitude, they are
corrected to read equivalent sea level values. Station Pressure is the
actual, un-corrected value the instrument read. Station Pressure is needed to
calculate the density altitude that is also printed on the timing slip.

What is ST on the time slips, they are asking on the net.
