Hard for me to word, so I have attached an entity to reproduce:
1. load thrust tester
2. add 4 thrusters to the core. Thrust should be 20.2ish
3. Remove the 4 thrusters
5. Toggle inherited thrust
6. Total thrust with the other docks 4 thrusters is 22
With this there really isn't any reason not to use docked thrusters and they seem to have a clear advantage over just putting them on the main ship to squeeze out the most possible. I'm not sure if this is intentional but from a balance perspective it seems to be a bit off.
