I have no idea what washout speed are or should be. So I just don't take a position in any discussion about it, leave it to others...

I read something similar, except it was 1/3rd as sensitive, which roughly collaborates with what L/W seems to be shooting (2Nrd difference = 4dB, = 2.5 times difference), but that correlates with a lot less than 3 times, depending on conditions. 10 times might hold true at higher speeds or in wierd hydroacoustic conditions - hard to see it in normality.

I have read that Russians thought it was 10x det range, but actually it was not that bad and about 3 times

And I entirely agree with this general concept, except:
1) Does the mentioned difference (from the sources) take account the Display Influence?

Don't know, I don't touch sensors. But this influence SHOULD BE MEASURED I think, and measured on more than one comp to see if GFX card makes any difference between US and Russian interfaces.

OK, maybe not 55, but 50. This is like 10+-year old tech (French NTL-90 came in about '92), so even assuming the usual 10-year gap it is not unreasonable to assume the Russians would have gotten around to it in their newest ASW weapons. Besides, some sources suggest making a 50-knot small torp is not impossible for the Russians.

Only most modern electric torps like MU-90 with very advanced batteries are said to be in 50kts class speed. The torpedo used in SS-N-27 system is MPT-1UE very small electric torpedo, not designed for it and used previously in russian eqiuvalent of CAPTOR mine. Not most modern probably, some years design.
Very small, very light (that's why they used it instead of great APR family - oh yes, APRs ARE fast, but too heavy for that system... but APRs could be raplacement for Stallion torps).

From the link you gave, do you thought about 400 mm (15.75") APSET-95
torp ? Come on, 30.000m of range for 400mm torp ? It's very questionable one, probably two different torpedos are mixed here, the name from one and specs (guessed) from another...

Since MaxDepth in DW = Max 100% Safe Depth, I suggest initial calibration can be set for Never Exceed Depth (in the Ak, it is 1804 feet according to GlobalSecurity, which is similar to what's there now).

Fine calibration between that and crush (estimated at about 1970-2160 feet) to aim for a 50% chance, with the condition that Never Exceed Depth should be perfectly safe.

For those without Never Exceed Listed, I suggest starting out halfway and then calibrating within the gap between test (300m for LA) and crush (450m) so that at the real crush, we get roughly a 50% chance of death as possible.

100% agreed I would like to do it exactly this way !
