My ALO was great at making sure I was pursuing solid backups, had all my nomination packets in order, prepping for interviews, etc.
If you don’t know/ have anyone with knowledge about the Service Academies, involved in your application, ALOs and BGOs are great people to run your thoughts, questions, applications confusions, etc. by. If they were originally from your area, that also puts you in a spot to glean some knowledge.
I didn’t contact mine more than once a month, but having a direct contact is quite helpful at times. It’s personal as to how much you need it, but getting answers from an ALO is so much better than making assumptions on your application.
