Incorrect Winds

Can someone confirm that winds are accurate?

I do only real world flights and winds (Live) are usually on the money, maybe off by 2 kts. But I’m getting headwinds of 40 kts and my speeds are 460 plus kts while the real world counter part is at 405 ground speed.

Live now I’m flying the E175 SKW3498 real world now samething.

They are. But there might be differences due to update cycle delay.
