It would be helpful if your data can be substantiated with some literature. From the little interaction i have had with pilots in India and US, in BVR combat, practical engagement is usually at half the distance of the max BVR, pilots would wait till the last minute, as it reduces the response time for the opponent for counter measures as well as evasive maneuvers. So it boils down to who can see farther and has longer range, along with that R27ET/ER can be launched without a lock and achieve a lock PPS: In this mode which gives an incredible advantage of fire first and lock later at longer engagement ranges, especially when adversary turns on their radar.
As far as Missile comparison is concerned, although older Rvv ae are comparable to Aim 120C, the newer lot of RVV AEM1 with multi-function doppler-monopulse active radar seeker have better performance than RVV AE, addtionally Python IV currently posses the best all aspect seeker in the combat arena as of today and is also qualified on the MKI.
