I haven't yet participated in competitions but had been planning to, primarily for the critical feedback. It's disheartening that I hear a lot of stories regarding the lack of helpful feedback from these competition judges.
My suggestion is to
1) ignore old anecdotal stories on competition feedback, and
2) unless otherwise stated, assume the competition is just that (and feedback will be minimal).
In 2022, for the competitions that I follow, the competition web site often contained a link to the electronic scoresheet participants will receive.
In 2023, if I enter a competition and I don't see that information at the competition web site, I will ask them.
