fighter agility

1 ) For dog fight In WW I the most important aspect of fighter is max turn rate , by the start of WW II top speed is the most important thing ( hence the saying ” speed is life ” ) . 4 gen fighter design seem to emphasize on sustain turn rate , why is that ? What caused these changes ?

2) with only enough fuel to fly about 500 km and empty weapon rack ( without missiles or fuel tank but the rack still there ) what are the max turn rate , sustain turn rate , acceleration of fighter like su-27 , mig-29 , f-16 , f-15 , mig-31 , gripen , rafale , typhoon , f-35 , f-22 ? ( no need to be very accurate , can be estimate number by yourself )

3) f-22 actually have worse aerodynamic compared to f-15 right ? ( i mean it seem that f-22 only turn better due to tvc and fly faster as F119 have much higher thrust than f-15́s engine

4) how long can fighter listed above turn their after burner at max ? ( with and without external fuel tank )

5 ) are plane like x-29 , su-47 , x-41 alot more agile than normal fighter ?
