I wasn't aware that there isn't an 'overall' rating that gets produced based on all the category scores - that's how every other jam I've participated in so far has worked. If this is the case then it's not really a problem.
Ah. The soft 'overall' category was removed since the 2022 jam. I take back my previous comment :) See the 2021 jam for how it worked:
