i used to go whenever for materials on pervious saves, but tbh even then its only rly useful if ur lacking weeds or want to hunt for recipes. since im try to get every villagers' picture i'll only rly use nookmts to get a new villager since the campsite villagers may mess things up (unless they appear on a day i have an open plot). im trying to hoard my nook miles atm because when i eventually get everyone's picture or give up on trying to get everyone's picture i'll want to hunt for my dreamies.
