I think the velocity profiles are fine, but the starting sound levels are too low in my opinion. I couldn't detect a 1-knot non-improved Kilo in a test I just did at 2.5nm with the TB-23 (sea state 3, both platforms at 150ft).
By the way, if you right-click on a platform in the editor, there is a button that allows you to get the maximum sensor range for each sensor targeting another in-game platform. Unfortunately, this feature doesn't work. I ran a test with fishing boats, one a bit outside and one a bit inside the TB-23 circle, and both of them shows the 50Hz line. If I remember correctly, both showed at least a dotted 125Hz line too...
