Is taking the time to remember your seed phrase a waste of time?

According to The Rule of Three for making backups, you should have three copies of any piece of data with at least one in a separate physical location from the other two in order to guarantee that it is not lost. But the problem is that the more times your write your seed phrases down is that it makes it more likely that they'll be stolen. So would remembering your seed phrase through rote memorization be secure enough to count as an additional backup or is your memory not reliable enough to be worth the time?
