You're excused. No it is not.
"Is the field now maxed at 56? The article (http://nasportscar.com/2017-weathert...before-the-24/
) states "mandatory test" which I don't remember (one way or t'other, 'know it's so for Le Mans) and am curious if any add'l entries would be allowed"
The answer to my question by Coach:
**MANDATORY: Entrants participating in the 24 Hours of Daytona on January 26th -29th are required to participate in the January 6th-8th Daytona Test (“Roar”).
Of which there were 56.
