I havn't been able to be much involved lately (rehearsal season has started) but I'll toss my 2 bits in on this.
I would very much like to know what a "historic" intercept chance for US subs on Ultra convoys was. By my experience it is about 1 in 12. You can travel to the area indicated and yet still miss the convoy entirely if it is beyond your detection range.
I know the many boxes and diamonds on the stock game are not realistic and gamey, but it would be nice to be able to at least draw a plot on that convoy from Rabaul to Pelieu. Even if its 800 miles and frought with margin of error, at least I would feel I was putting myself in the best chance to succeed.
Hope everyone is well!
