Automatic countermeasure settings?

So I’ve never really messed around with these settings, I understand what series interval, series, and interval settings do, but I’m not sure about how countermeasure mechanics work in this game to be able to intelligently set these up so I’m not wasting flares or chaff when turning on periodic countermeasures.

Does dumping a boatload of chaff or flares actually help vs just having a few in the air, I have no idea how long flares or chaff even really last in terms of spoofing missiles, or if having more in the air at 1 time does anything, what intervals are best for keeping IRCCM missiles in inertial mode etc.

Anyone have any input on this subject? What settings do you generally use etc.?

Personally, i never use the automatic flares systems.

Putting out a lot of flares can create a path for the missile to follow to your plane.

Depending on the missile? Just 1-3 flares pops is enough.

This depends on what kind of IRCCM it is. For stuff lile the r73 and magic, you really have to flare before it gets with 2km behind you. From the front, they are basically like an aim9l so it isnt hard.

For the aim9m, you have to change course when you flare but you will just have to flare once or twice.
