That is really useful information, unfortunately that means turning on thrusters before hitting the Nav computer's Transfer Point. The less specific thrust, the earlier you have to hit it, and there isn’t a way in game to accurately measure angles in a user friendly way. Burn too early, or too late, and you feel tempted to make course corrections on the fly, rather than reloading a quicksave. This reminds me of the discussion last year, or was it 2020, we had about a generalised Gravity Assist Calculator.
