Hey all,
I have started playing SHIV again after a few busy weeks, and most importantly RFB, and I am loving it. Following my current patrol, I have a couple of questions on detection. Although I have no problems with shooting torpedoes and sailing off when the party is over, I am struggling a bit to intercept convoys properly.
I am either too accurate, or very (un)lucky, but I always end up spot on the convoy's trajectory when attempting to ambush it. The consequence is that it then always seems to be sailing directly towards my position. Being on their path, the escorts always starts pinging and detects me before I can even start identifying my targets. Just recently, the same situation occured, and I ended up with 7 destroyers on top of me : fortunately, their large number prevented them from maneuvering and bombing me efficiently, as I could admire on the surface, and they eventually left

.
Now I have read articles about the detection devices used, and Ducimus' article about the "uber" AI demystified", and think I am pretty comfortable with "evading" (generally

), my problem is avoiding detection in the first place.
Even if I am sitting like a rock in front of an unsuspecting convoy, they always end up seeing me and raising the alarm miles away.
1 - What am I doing wrong ? Should I try to intercept the convoy making sure I am parallel to their trajectory, or should I try to intercept it on the outside?
2 - What other parameters/actions might affect the likelihood of the escorts detecting me in the first place ( profile parallel/perpendicular, silent running on/off, etc)?
3 - Can checking for the depth under the keel result in detection (I do not know the specifics, but I am guessing the signal just bounces back up to the submarine, so I was wondering whether it is the same in RFB : I just want to make sure)?
Thanks in advance for your help

!!!
Happy hunting!
