When using mods like SCANsat, I find I spend a lot of time having to wait for my spacecraft to complete a certain number of orbits in order to complete whatever task it is I launched it for. To minimize this time, I want to find out what altitude is best to orbit at, such that the orbit period divided by the maximum time warp multiplier results in the least amount of real-time spent per orbit.
I know there's plenty of charts online that provide the values for maximum time warp allowed at certain altitudes. What I need now is a reference or formula to get the orbital periods at those altitudes, so I can figure out which will have the least real-time orbit period.
Is there an easy way to do this, or is this one of the harder bits of rocket science that I'm going to have to learn some advanced maths for?
