I too find the Ultra messages helpful. Even more, knowing the historical concentrations of shipping at certain times. SH4 has similar enough traffic you can take advantage of that. There are web sites where you can get maps of historical traffic. These have worked well for me. Early purchasers of the game got paper maps when purchasing the deluxe version. Some players have offered to send scans of this map to people requesting it.
