Very poorly written report. I know it is only preliminary, but they add more confusion to the matter instead of answering any questions.
They left so much crucial information out of the report that it makes it impossible to understand. It sounds like the Onboard Perf. Tool gave them data for 9 from T1. But the report mentions a NOTAM and does not go on to say what that NOTAM says.
Hopefully the FAA will release their own report and investigation.
