The range of submarine noise levels is HORRIBLY compressed. A Seawolf is 55 Passive SL base. A Victor I is like 62 or 63. In LWAMI a Seawolf is 56 (+/-1 don't remember), and a Victor III is 68. Theoretical noise rise with speed is similar to LWAMI (+15-+25 at full speed), but darn if I saw that effect last night.
The Seawolf passive SL is 55 in the latest LWAMI. Believe me I modded it once to 50 and 53.

If you didn't notice signal difference between slow moving and fast moving target you were probably too far out so you were only detecting a long(long/far is relative and it's substantially lower for RA than LWAMI) fast moving noisy target and wasn't able to detect the slow moving one at all. To compare both target must be duly detected. The difference may not be noticeable in STA but most probably be visible either in ITA or LTA mode. Like wise many detection will occur solely in ITA or LTA first before becoming visible at all in STA. It's a different game with different rules and estimates.
