It occured to me that judging mission 'score' by the time taken is wrong. On mission 5 I hae completed it twice- once keeping to a reasonable harbour limit of about 6 kts and another time at full speed, straight to full astern to slow for turns.
Got better time on the second run but wasn't realistic.
I think (maye for 2009....) judging performance on fuel usage or something (like they do for real) might be a good option.
