800 images - is that all - a walk in the park, or I guess in this case the zoo. (Tongue in cheek)
I came back from Africa with over 3500 images to go through, granted it was ten days of photography, but after 4 trips to the Dark Continent, I am a little more fussy than when I shot over 5000 on my first trip. My friend, who is a professional, probably shot more than twice what I did, but then he is more deadly with his editing than I probably am. He is looking for a few special images and if they aren't there, then the image is gone - he probably keeps less than 10% of what he actually shoots. I remove all the "bad" ones - out of focus, body parts cutoff, pokies, etc. and then still only process 10-20% of the images. Lightroom is your friend.
My friends wonder why it takes a few weeks to get a selection up on Flickr - I suppose yours do to.
Tom, I am like you, I enjoy the challenge of processing my images and just love to experiment with them.
