Observation:
I played a Tambor for 2 Patrols in TM 1.0 and was luckily in port for 1.1.
Assignments: Patrol 3 was Formosa Commando Insertion, Deploy Formosa Sea, Prosecute Shipping. Nice.
Mileage: at start my CE calculated 11200 at 10kt. I ordered 45% throtttle (my std), and that figure shoots up to 13600 at ~9.4kt
I do not believe the range@speed settings used in *.sim are the most efficient settings in game as is commonly thought. They CAN be, but when they are it is co-incidental. I believe that efficiency is directly related to throttle %, such as is used in the *.cfg file. I could be wrong but...
At any rate the max range is actually almost 20% higher, IF you have a good CE

Dunno what you want to do with the info, but there it is for you to consider.
BTW, nice job on 1.1- I am playing with only my keyboard and camera on top. (and sub throttle speeds in the cfg lol - i use them as creep, stationkeeping,maxrange,full & flank .125,.33,.45,.9,1.0). Once you get use to this everything else is a lot of unneccessary dial clicking. Old habits and crutches - with them everything just felt right.
Again, nice job.
