I'm having a problem with planning a gravitational maneuver for Kerbin-Eve-Moho flight. Using "Solar system edge" tutorial as a reference, I managed to create a somewhat realistic plan. The problems started when I realised that my craft would not be able to do ejection burn at once and tried to assemble a flight plan with split burns. While fist two stages of building flyby trajectory (finding Eve and fitting inclination, RAAN and argument of periapsis), constraint violation cannot be lowered down to zero when performing optimization against SMa and eccentricity. I tried changing objective function, but it doesn't really help: only "Minimize distance..." gives somewhat better results. Still, the resulting trajectory doesn't bring me in vicinity of Moho. What I also tried: changing time of 1st ejection burn, tinkering with objective functions, replacing SMa with radius of periapsis, building coast to next ejection burn via "coast to apoapsis"+"coast to periapsis", and via "coast to periapsis" with Revs prior to coast = 1.
I'm using stable version of KSP TOT 1.5.8. MFMS summary: https://pastebin.com/y0E7jYtw, plan with a single ejection burn https://drive.google.com/file/d/1F_05C_G0AXd7A_SOG3xyZh2NknrRBT_X/view?usp=sharing, plan with 2 ejection burns https://drive.google.com/file/d/1BalsGEEYSLUgIBmnk96tQQRE_3XOqw8g/view?usp=sharing
What advice can you give on planning multiple-burn ejection trajectories? What has gone wrong in this case?
