Hi everyone.
When you use the spreadsheet to mix different engine types together, it uses the delta-v of one or the other.
For example, if at TL9 I have 2 hydrogen fuel tanks, 1 nuclear lightbulb engine (0.45 mps per tank) and 1 nuclear thermal rocket (0.8 mps per tank), it lists 0.9 mps and 1.6 mps in the list of engines, but the final delta-v is 1.6 mps.
What would the actual delta-v be? An average of the two? (since they are sharing the same tanks?)
