I got a 'Major Victory' (200 points), on the 7th attempt, even though time ran out on me before I had completed the ex-fil,
although it looks, based on your post, as though I may not have been penalised for this.
I had completed the two 'surveys' OK, although the airfield got blasted, so it looks as though the scoring is right although
I'm a bit doubtful about the triggering of the missile launch (see below)
This was a bit odd. The missiles rained down just before I had reached the first 'survey' area although it didn't feel like
I had been discovered as no attacks were made even though I had remained at periscope depth throughout. And there were plenty of
aircraft in the air . After exiting the first survey area, I then moved to the second one without serious harassment which
again made me feel that I probably hadn't been spotted.
Are your new instructions OK, however?
The wording implies that you should start the scenario at periscope depth and remain there, subject to not endangering the sub, until you have completed the first survey task.
I'm a bit doubtful of the viability of this, however, unless the time is extended. But I didn't exceed seven knots at periscope depth, and more normally four in daylight, so it may be that
I am too conservative.
Paradoxically my most 'successful' attempt was the eighth although I got nailed on the exfil. I was trying to complete the scenario in the time available.
In this I ran up to the 'border' submerged at maximum depth using cruise speed and then went to periscope depth/creep there, as I had exhausted my
batteries in any case. I carefully manouevered through the fishing fleet and completed the first survey, then made a submerged run,
during the remains of daylight toward survey location 2. At this point I came up to periscope depth, completed the second survey and
then fled after about 30 minutes at creep, towards the ex-fil at cruise speed and promptly got nailed (which was fair enough).
But even then I was only barely going to make the ex-fil area before the time ran out, but then that may not actually matter.
A most interesting scenario, however and infinitely replayable.
