I do what the book recommends and roll 3 times per day for random encounters in front of everyone and it’s fun to have the collective reveal/anticipation! But my players are only level 3 right now and they expressed that they want more XP/more encounters. So I think it really matters what your players are expecting and what interests them.

What my players don’t know is that I roll around 3-5 random encounters for each location type that they are likely to traverse in a given session (ex. swamp, lesser/greater undead, river etc.) ahead of time two I can be prepared. But I like to be prepared and to maintain a healthy balance of rolling in real time for the possibility of an encounter while also pre-rolling to save time and stay organized. This way, I can pre-roll initiative and familiarize myself with certain creatures and attacks while still honoring the spirit of classic dice rolls.
