Dive Times Reality
US Boats in the Pacific AOR dived slower than there German counterparts in the Atlantic - one reason for this was the better radar and much longer distances in the PAC Vs. LANT. Consider that the Germans were faced with a massive Air ASW threat which forced them to dive faster or to eventually design a boat that was better submerged than surfaced (the 21 class). The game(s) reflect this pretty well. Even at Flank it takes a while to get down. Referencing Ned Beach's issue we still experience problems at times - particularly coming to PD and passing a layer. A temperature gradiant can add or subtract thousands of pound of weight which can cause a "stall" and have the ship stuck at a less than optimum depth. Might be a real pain in the but to model that and frankly probably not worth the time or required processing.
