Hi guys
IIRC the maximum number I have had looking for me was 9 when I did EBCW and I did eventually manage to get away at 1 knot zigzagging, starting and stopping.
I have put together a tutorial that some of you might be interested who use map contacts which should give you a better chance of escaping when used for attacking convoys.
This is an alternative to the 90 degree fast shoot with a 45 degree one.
With this there is a good chance that any escorts will look for you in the wrong place.
