I must add this previous post from Don Sofranko to this fact:
Re: "Live From" Indy US Nationals The Big GO 2022
Just a curious question after watching the big race from home on NHRA tv

As a past racer at the big go, its always a challenge with the big delays in hours or days between rounds. I was amazed that a bunch, if not all the guys on Monday slowed more than expected, from the early Monday R4 to R5 (3:30 PM) in super stock, and also similar in R5 to R6 Stock. It seems like with all the modern weather stations, and other data that it would have been detectable, to see a slowdown.

Am I wrong or is there another reason for everyone missing the dial by what looks like .03-.04?

Why do the modern weather stations not always tell the picture?
This was from early Monday to the 3:30 afternoon round
