I don't zoom in the map to where I can see the hydrolines or the little boxes for the whole convoy, but I do have the single box or triangle on the zoomed out map representing the entire convoy.

GWX, and most other ubermods, erase the tales in the non zoomed out view.

I'm a fuel miser too, so I try to set limits for food etc.

I stay at sea, in a type VII, a maximum of 56 days. (I believe this became a directive later in the war)

In a Type II, I try to keep in around 21 days.

Because I don't zoom in with the Nav Map, and intercept course that I think is right on top of someone, might be 25km alway. Plus sometimes you get the convoys that alternate courses between E and NNE or something to that effect. If you zoom in all the way on the Nav Map, to just before the hydrolines appear, I think the intercepts are too easy to plot.
