....Anyone that has had to work with the NFPA's Electrical Code for any period of time would consider the ICSCC Regs, and most other race sanctioning Rules/Regs as comparitive 'light' reading......
My dad, my brother and currently my son have ALL dealt with the NEC on a professional level at one point or another in our lives.
I find it to be a well written, well organized encyclopedia. The only thing that hurts it is 'local regulations' put on top of it.

When you fill out the paper work for your ICSCC license they ask you to 'request' 3 possible numbers. They will give you a number that's available in the order you request.
If you choose to race on your 'current' license and not apply initially for an ICSCC license, you'll be running a 7xx number. Currently there are ZERO 7xx numbers in Group 6. So, for an entry you could use your currnet number with a 7 added on.
Should you decide to join an ICSCC member club, select your number choices by looking at this list:

There are NO duplicate numbers in a COMPLETE run group regardless of which class you're in. So look at the list then request 3 number possibility's that are not on the list.
P.S.
The three digit numbers starting with "3" are reserved for novices.
P.P.S.
The ESR's are a gaggle of Legends cars that are a blast to watch and race wtih.. GOOD GUYS all.

FL is an 'open' Formula Libre class. Open to ANY open wheel car. So you get a lot of people entering FF's, FM's, FC's, etc and running TWO races. One in there class in Group 3 and FL in Group 6.
Sadly, there is not 2 run groups where sports racers are eligible. But you might advise your open wheel buddy's up there that they can 'double enter' in ICSCC races and get 2 races per weekend (about 3 hours track time) if they are inclined to do that (discounted entry fee).
Sports racers can get additional track time by running the 2 Enduros. Perhaps in a Fusion?
