It’s not just my own experience when I say that using the 1 to 5 star pick system in Lightroom (or any other application) to decide whether a photo is a pick or a rejection can be a hassle.
In first instance it may sound harsh but my selection process only knows 2 kinds of photo’s. Winner and losers. If you want to put it that way. Once in a while, of course, there are photographs where I don’t really know if and when I will use them in the near or far future. Those photo’s become the one-day-maybe-images.
However, giving them then a certain amount of stars just adds to the hassle of having to rethink the whole process again once I come back to them. Of course this is my opinion and not it’s not the rule at all.
