It can be done, and not with much effort really. If you just spend maybe half an hour per-day browsing through them for one week, an accurate representation of your own view on what you believe to be the best shots will be undoubtedly realised. In the most general sense, I often divide artistic judgement into two stages: Immediate appeal, and Long-term appeal. For instance, you may like one image A and dislike image B at first, but then not after too long, your preference may swap. While I do believe that long-term appeal is more meritable than immediate appeal, both need to be taken into account as being positive factors, regardless whether or not the shot you felt immediate appeal for now holds much less appeal. From what I've seen, most people just disregard this and always believe that their current mindset is the most correct, which is just dumb. All mindsets are equal, as they are what you truly believe at that time.
At least, that's just how I see it.
