STD/STP are always higher because it is based off a colder temp, 60* iirc. Why would you base the HP numbers at 60 degrees when most summer street tires start to lose their grip at that cold temp?
SAE is based off 75 degrees and while it doesn't give users the warm fuzzy feeling of a higher number IT IS the standard of automotive manufactures.

Simple mathematics my friend, Power to Weight.
If we used SAE numbers our cars would be going to fast for the HP recorded.
I think you miss the whole point of a correction factor.
It is simply used to give you a constant from cold weather to hot weather low humidity to high humidity, low baro to high baro ect, it is NOT a REAL Number.
Like I said earlier there are a multitude of correction factors used across the globe.
We measure actual numbers and as I said STP were within 1% of actual because we happen to be very close to a standard day here for this Region.
Again Corrected numbers are NOT REAL, they have been adjusted to revert back to a certain set of parameters.
Also note that if the Baro sensor, Temp Sensor, Humidity senors are not calibrated the Corrected numbers can be either higher or lower than actual even if you test on a standard day.
