Please forgive me if I am asking a dumb question. I am a little curious about the orbital parameters of "LEO" used by SpaceX on many occasions specifically those related to payload capability. According to SpaceX's Falcon 9 newest user guide it appears, though I cannot confirm, that it refers to a 200km x 360km orbit:
but on this website it hints to be a 185km x 185km circular orbit (a little dated):
So which one is more accurate in terms of payload capability? Thanks.
