Playing on PS4 with latest update, career mode.
Problem is the rocket engine seems to burn twice as long as it should.
Use a LV-T45 engine with a liquid fuel burn rate of 6.166 units/sec., and an oxidizer burn rate of 7.536 units/sec.
Use a FL-T100 fuel tank holding 45 units of liquid fuel, and 55 units of oxidizer.
45 units of liquid fuel divided by 6.166 units/sec = 7.3 second burn time.
55 units of oxidizer divided by 7.536 units/sec = 7.3 second burn time.
The fuel and oxidizer mix and burn together, so the total burn time should be 7.3 seconds.
When I launch the rocket it burn for 14.6 seconds.
Where am I going wrong?
