How do you use DEMON strength to determine closing/opening course if he is also accelerating?

here some logical conditions I've learned about DEMON and threat anticipation(I'd like to think of it that way)

initial state: the threat is at cruise speed of X knots, and has been detected by you, you have BB contact and firing solution, DEMON waterfall is depicting TPK data and lines are spaced.. speed from TPK should coincide with the following conditions.

IF DEMON waterfall = expanding, threat is accelerating
IF DEMON waterfall = contracting, threat is decelerating
IF DEMON waterfall = contracting and disappears = threat rigged all stop or changed layer
IF DEMON waterfall = brighter in color, lines are widening, number of lines increasing (7 max for subs), threat closing
IF DEMON waterfall = darker in color, lines growing narrow, number of lines decreasing, threat opening

*all conditions in combination to determine intentions of the threat..

Once you reach your conclusion based on the info your threat is giving you, plot a counter strategy & attempt for a master solution.. but if its a DM style scenario and you know the 1st contact on your TA is hostile, plot solution(TA only), engage, keep the target under pressure and close the distance for a better solution(attempted master)

I'm pretty good at determining opening/closing while building my firing solution, but once he starts evading I can't tell anymore.

I think it really depends on the weapons you are using. All that matters is who can get weapons on target the fastest w/o getting hit. Akulas(Sturgeon, Virgina, SSKs with TAs in RA mod) will be your prime candidates for that. Soon as he starts evading you'll start losing contact and will need to regain if completely lost. If the oppty presents itself, try to pursue at optimal speed while he is deaf and running. when he starts to ramp down to a reasonable speed where he can hear again, rig all stop and refine your solution. Hopefully the SSP type can assist your further in your approach. Worst case go active and readjust wire-guided as goldorak suggested.

If I don't detect this and enable the fish sooner than my RTE, he sometimes can get close enough to slip past once they start snaking.

I need to ask, what sub are you using.. because this situation can be handled differently based on the sub you are driving. Soon as you tell me what sub you like to drive then I can better be of assistance.

I just started playing around with a scenario using the Kilo Improved for primative ASW against old diesel boats like the Daphne. In some ways it's actually easier.

I'm sorry I can't help you with diesels, TLAM strike and molon(i think goldorak also) are diesel men and probably can provide better advice than I could. I've had intentions on learning diesels but haven't done that yet. My impression of diesels is they are not made for ASW and the only time you'll get wind of a nuke is up close and personal. AFAIC, Diesels don't have enough up-ramp and speed to clear bearing quickly. Your best attempt against a nuke is a coordinated effort with air support or a listening platform, or ambush based on intelligence data.
