The corrected statistic for Class Disparity is 30% GTP cars, 70% GTO cars. This is pretty much in line with what I would assume this series would accumulate if it operated in real life; the SCCA Mustangs are afaik a defunct racing series, but chances are high there are still cars out there doing random time attack events, hill climb competitions and track days. Drivers who still own those Mustangs would probably enter this event, but there probably aren't many of them. Meanwhile, the Late Model Stock cars are the current chassis being run most popularly in CARS Late Model Tour races, so there are a LOT of people who'd probably run in a few NACRS events as either one-offs or part-time entries just to take their short track car out to a road course for some fun racing.
With the GTO class, there is actually a pretty nice disparity between the manufacturer decal sets. The most popular decal sets were the old Ford Fusion, the new Camaro ZL1 and the new Camry. Someone accidentally picked the Mustang decal set despite being in GTP class though, so the pie chart is a little bit off because of that. The new Mustang decal set and the newer Ford Fusion decal set are both the only decal sets who weren't picked.
Now, about those driver skill ratings... YALL ARE TOO HUMBLE LMAO
This range of skill means that there'd be a lot of AI-to-AI fighting in the back of the pack, but a wide disparity between the lead pack and the mid-pack. Not to worry, everybody's AI skill level will be adjusted before the first race to make the fighting happen a little bit closer to the front. The skill rating you picked was intended to be used as a reference anyways, in just such an occasion where changes needed to be made to improve the racing.
Thanks everyone for submitting your drivers! The first NACRS race begins at Long Beach, since NAGT was going to be running at a street circuit that currently isn't available in iRacing. Welcome, NACKERS!
