I can't imagine a real time whole patrol but I exactly know what you feel. 1xTC is a totally different game. Today I've spent the whole day reading stuff about celestial navigation and trying to get my boat to the patrol point. I don't use TC more than 256 and travel times are long enough. But considering manual navigation and target finding without any indicators on map I need 1xTC. So most of the juice is real time.
OK got to change course in 3 minutes, I'm trying to find that small island SW of Lerwick as my orientation point... yeah am lost
