Indeed; I'm interested in monitoring this before conjecturing too much. At least in the Midwest, SC season was down 20-25% as well after the first event of the season, so it's a continuation of that trend.
Like I said; interesting to monitor
38 at Louisville, down 29% from 54
53 in Cambridge, down 27% from 73
45 at Tulsa, down 24% from 59
56 in NorCal, down 30% from 81
29 in Florida, down 25% from 40
Overall first weekend: 221 participants in 5 regionals (307 last year, -28%)
