I can also think about another format, but from my experience people are very attached to this format.
Yeah, cos most people who play SFS like simple. They're not interested in phase angles, they just want to know how much its going to cost them when they press burn when the game tells them to burn.
I tried other map formats, even some more complete that showed transfers "from X to X" (and not just "from Earth to X"), but the result was very confusing and hasn't really been appreciated then...
Yeah, I remember the thread and the other concept drawing that was put together. Personally didn't mind it, and would come in handy when doing deliveries that didn't involve going back to Earth first.
You only need 1 dV value for the most efficient phase angle.
Why not the least efficient? If you only show the most efficient on a potentially quite elliptical orbit then there'll be a huge difference between best case and worst case in terms of fuel/Dv budget.
You can. There's a timewarp.
And if you don't feel like waiting for not just a normal transfer window, but the
perfect transfer window where everything is aligned? Which, depending on the bodies concerned, may be quite a wait. Even under timewarp
Altaïr does Dv maps out of purely good nature, and is conceptualising a way of not just calculating, but presenting a workable map for anyone to use.
If you want to wait for the right phase angle, cos its best in KSP, do so. Hopefully the game will show you how to calculate and present that aswell in SFS. No one is going to force you to use his map if you have worked out something better.
