New to Letterboxd… what’s the “acceptable” way to log movies?

Hey all, sort of an odd question but was hoping to have some guidance on this. I just started made an account on Letterboxd today, and was curious as to how most people go about rating and or logging movies?

For example, I’ve watched a great deal of movies that I am able to rate easily from memory however if I just go and rate 300-400 movies in a day does that kind of invalidate my rating/loggings? In which case I just rate as I watch even if that means going back through movies I’ve seen a bunch?

Sorry if this is silly or doesn’t make sense! Hoping someone will be able to provide some help!
