Hahaha I spent my early life on the Wilmette/Evanston boarder and will possibly be moving to the LA area near Arrowhead soon. It was interesting because I remember how ISI heavy a lot of those rinks were. DuPage Open was the huge USFS competition. My parents were shocked to hear about Jason, Bradie, and Gracie because they were so used to no one doing USFS up there! Is it still ISI heavy up there? Maybe that's why there in't a huge ladies field.
@StitchMonkey I wonder if they've been changing the whole Nationals placements thing. Certainly they still consider it, but I've been noticing that they've been taking risks with who they're sending at the lower levels. Not that they're sending bad skaters, just that they've been sending skaters based on summer competition performances and other monitoring sessions/training camps. It seems they're mainly using this approach of camps, competitions, and monitoring for lower levels. These changes seemed to coincide with changes to the high performance staff a few years back.
For Senior (and to some extent Junior) it's harder since there's rules about picking competitors, but USFS has been taking risks where they can with the host spots at SA and sending both lower and higher-ranked seniors to as many Senior B's as possible. It also seems like they're really upping the number of Novice (or intermediate age-eligible for Novice) skaters they send out to compete internationally.
So while I do think they'll look at Nationals placements I think they'll be taking the summer competitions seriously. It certainly paid off for Bradie, and Mariah got a GP medal out of her host pick at SA, so I see no reason for them not to consider summer. The biggest problem, as others have mentioned, is that the US Ladies eligible for that spot have been something of a mess this summer. TBH I couldn't say who would be best to give that spot to.
