Your memory serves you well. But note this is the bare minimum. It is like a doctor telling you that you need 500 calories a day. This is not a recommendation, but a warning that we should take in our food (spiritually or physically) much more often to be fully healthy (spiritually or physically). Through the sacrament, we recall all that Christ has done and we abide with Him in a most personal and intimate connection. It goes without saying that a once-a-year reminder won't do.

I can appreciate the analogy, but I think it's not that strong. No doctor would recommend that 500 calorie mark as a bare necessity, as it would quickly produce disease, and then death, eventually.
And, jo, to my way of thinking, it doesn't 'go without saying that a once-a-year reminder won't do' because it does "do", in fact. That's one of the requirements that begets or doesn't beget being in communion with the Church. As I said, it just seems to be at odds with the idea that the Eucharist is the 'summit' of the life of Christian worship.
I recognize that this isn't something to be policed or that can be policed, but in order to inculcate the people of God with a high and strong attachment to the splendid gift Christ left us in the Sacrament, and to impress upon them the efficacy of the Sacrament as explained by Christ, that once a year requirement undercuts ALL of that, IMO.
