Very well done Sartoris.
the error is in the 30 Aug coordinate; you should set it to '48.45N 13.45W' instead of '53.31N 08.09E'. I am glad I have implemented the course plotted on map feature, because it makes it easy to spot and to correct always possible mistakes
A few more remarks:
- you don't need to select anything in the 'current activity' row for normal patrol coordinates: blank cells are automatically recognized as 'normal patrol' anyway. This will make you to spare the time to tag each cell
- similarly, when an attack is recorded in the 'number of ships sunk/damaged' row, you don't need to set its corresponding 'current activity' cell to 'attacking contact': the spreadsheet will automatically recognize attacks, as long as a numerical input equal or bigger than 0 is set. If the setting is 0, a failed attack flag will be generated, otherwise, the output used for radio reporting will be 'successful attack'.
- I have noticed that you have recorded the Estonian Ship "Hanonia", captured on 24 Sep 1939, as a 'sunk/damaged ship'. Since the seizing of ships didn't obviously involve the use of any torpedo, I wouldn't record them at all. Nonetheless, I can create a 'ship catured' input for radio reporting purposes, if you think it is worth it
P.S: another special tag I am thinking to add is "boat being refitted"
