Rafale sustain turn rate

How accurate are these information :

Dassault Rafale has corner speed of 330 kts for 11 g instantaneous turn, and 360 kts for 9 g sustained turn. This gives it instantaneous turn rate of 36,4 deg/s and sustained turn rate of 27,3 deg/s. Sustained turn rate is achieved at >25.000 ft.

Rafale achieves 1.090 km combat radius in low-level penetration w/ 12×250 kg bombs, 4 MICA, 3×380 US gal tanks, which would be a standard ground attack mission profile for Rafale in presence of air defenses.

Rafale can achieve 5,5-6 g sustained turn with 3×2.000 l external fuel tanks, 4 air-to-air missiles and 2 SCALP cruise missiles. F-35A can only sustain 4,6 g when in clean configuration.
