SPO-15 behaviours between "Stock WP" and "Automatic"

[Firstdate]

Hello to all !

I'm trying to understand how the SPO-15 works with the ED documentation and test it in game to be sure to well understand. But I can't explain some in game behaviour compared with what's written in the manual, let's take an exemple :

First situation :

ME : Mig-29A with "Stock WP" SPO-15 setting
Threats: AI F-14B with radar homing continuously activated

Symbology shown :

At 195km from the target : "X" blinking -> It don't know if it's a Hawk radar OR an HPRF radar situated far away (mis-identified as type Х at low power levels), is that affirmation correct ?

AT 60km from the target : "X" still blinking and "F" lights up steadily -> Identified as a 4th gen fighter.

Second situation :

ME : Mig-29A with "Automatic" SPO-15 setting
Threats : AI F-14B with radar homing continuously activated

Symbology shown :

At 195km from the threat : "X" blinking -> Same reason than the first situation ?

At 60km : "П" lights up steadily and the "X" continu to blink ->  Why ?

At 20km when I get  the track warning, the "C" appear steadily -> Why ?

For the same aircraft, already registered in the "Stock" data base, the behaviours are different between "Stock" and "Automatic" SPO configuration... The automatic configuration isn't supposed to only add more datas from the stock version ? Why change the SPO behaviours for the same threat ?
