There appears to be plenty of people talking/speculating about things that they have no knowledge about.
My recollection is that there was a public statement by NHRA that a report would be release in XX number of days. [was it 30????].
Then, before those days were up, the lawsuit was filed, so there goes your 'public' report.
This case was to start on Monday
Civil Case Detail.
I do a lot of work involving litigation and, without detailed knowledge of the circumstances, it is pure speculation to guess why the case settled.
The plaintiff's would have known for some time the findings/opinions of the defendants. That information is typically exchanged WAY before a trial occurs.
