Looking for Feedback!

Hey y'all,
I am starting plans for PASER the Can Am race scheduled for April 25th here at Inslot's Checkered Flag. Some feedback from Saturday's Sportsman race would help me a lot with my plan. I sent out an email to those that I have email addresses for. If you didn't get it that means I don't have an email address for you!

How did the doors open time of 9am work for you?

How was the race starting time of 10:30am for you?

What did you think of the 3 round race format, with 4 minute heats?

What did you think of the random starting line up for the first round, followed by me setting the line up for the final two rounds?

We finished up around 5:00pm. What time would you prefer as a race end time?

As far as the race schedule, how do you think the race one round, break 1 hour for lunch, and then race the remaining 2 rounds worked out?

Any suggestions for the April 25th Can Am race?

Thank you for taking the time to help me out with this!
