I guess I don't understand the difference between a "standard day" and a "standard FAA/EASA day". Which number should be use for the takeoff run at MTOW?
The FAA/EASA figure is based upon standard atmospheric pressure, standard temperature of 15 degrees Celsius and a dry runway.
The standard day is based upon a dry runway and atmospheric pressure.
It's basically the same as they can calculate it for different temperatures as they have done. The difference is just 500 feet at MTOW so with this particular model it doesn't matter that much.
