You have a habit of Making lot of rubbish claims. Kindly quote where I said this.? From No Erieye destroyed to 1 destroyed, 2 badly damaged. PAF was force to admit down the years about the cover-up.
PAF Pilots and radar crew are not infallible. Their claims are not infallible. If you believe in their infallibility then sure we can Believe PAF pilots and radar crew.
Lets not get carried away. Pakistan was not cleared for AN/ALE-50 Decoy system and PAF never purchased it. Notifications from American side are enough indication what Pakistan purchased with F-16.
Explicit or Implicit claims will remain a claim until claim as you yourself said that SU-30 might have performed evasive maneuvers and at such a distance which is 70 KM + distance, A chaff cloud and SU-30 disappearing into mountain range to hide itself will obviously make the radar blip disappear or it crash landed back to airbase.
Hence relying solely on HUD and electronic Data isn't a fool proof way to claim something.
