ok for the alt calculation, Thx for adding comment
Alt seems OK !
The time to burn is not
Ie :
Mission: To Minmus! t: 52:06
body: Kerbin msl/ter: 200.43 km /200.18 km atm: (in space) v: 1,868 m/s
Node Burn: 0.0 s (41.1 %) dV: 0.10 (41.3 %) throttle: 0.01
--------------------------------------------------------------------------------
eject at phase angle 114.7 ejection angle -1.0 dV: 844.93 m/s
Maneuver: dt: 15:41 dV: 844.9 m/s stages: 1 burn: 49 s burn: 49 s
stages: [#1 dv: 845 m/s t: 49 s 1x Methalox]
Burn is planned in 15:41, but we miss Minmus.
If I use MNC to adjust, it's more 14:20 to enter SOI (without changing the dV needed, with circular and good inclinaison 6° starting orbit)
