Sonobouy ranges

Maybe some of the more experienced guys can offer some help here.
I have 1.01 with LWAMI 2.03.
After installing 2.03 and reading about the changes to the sonobouys- from the read me: THIS REPRESENTS A SIGNIFCANT GAME-PLAY CHANGE. To better reflect the way different sonobuoys are utilized in actual practice, the VLAD Shallow has been given the depth of 800ft, and the VLAD Deep has been given the depth of 1200ft, to prevent the use of VLADâ€™s in shallow water, as is realistic. The DIFAR buoy (90/400ft) MUST now be used in shallow water in the game, as it is the preferred buoy for shallow water operations in the real world. You may also want to take DIFAR Deep buoys along if you feel there may be a shallow surface duct and you want to have a good above-layer passive buoy option, that is a personal player preference. The DICASS Deep has also been given the depth of 600ft, to give an under-layer option for medium to shallow surface duct environments. Be aware, that this will change the game-play balance further in the direction of submarines for littoral operations, and possibly slightly in the favor of air-platforms in open ocean operations, given the option to put VLADâ€™s under layers in deep waters. Just remember NOT to load any VLADâ€™s if you are going to be operating in water that is shallower than 800ft. New buoy depths at a glance:
DIFAR 90/400
DICASS 90/600
VLAD 800/1200
I decided to run some tests to see what I need to do differently now.
I ran Beer's P3 Training Missions.
Noticed problems in mission 2, Barrier search for an Akula 2.
Akula is transiting East to West at 12 knots, 300 feet.
Conditions show a mud bottom, "bottom limited sound propagation", depths around 10k feet.
BT probe shows a linear line gradually rising from bottom left to top right of screen. (not sure what that means, but didnt look like a hard layer.
I turned "show truth on", then layed groups of bouys in front of the Akula's path.
Clusters of 4 bouys, 1 each of Difar S, Difar D, Vlad S and Vlad D.
These were tight clusters (bouy drop sounded like a machine gun), total of 3 clusters with 1000 yards between groups.

The Difars never turned "hot" even at 550 yards.
The Vlad Shallows and Deep both turned hot at 750 yards, only 1 VLAD shallow actually showed a "dot" on the 50hz line, this was at 550 yards. All other screens remained blank throughout.
Tried Autocrew, it picked up contact from the single Vlad Shallow, same thing I saw, at about 600 yards.
Repeated evolution again with second bouy line, same results.
Similar results in other missions, including MP6 and MP7 from Subguru.

Is the detection range for the Akula 2 at 12knots now 700 yards or less for VLAD, and apparently less than 500 yards for the Difars?

Could someone else look at this ?

Thanks guys, kinda frustrated here,
Swims

Edit* In the Minelayer mission, I was able to pick up an Akula speed 18knots at what I would comnsider "normal ranges", about 2.5nm on all bouys.
So if the Akula is at 12 knots it's inaudible at 500 yards, but at 18 its loud enough to hear at 4k yards???
