I have noticed there's a very very low correlation between how hard I try on captchas and how quickly they let me through. I just quickly mash a bunch of tiles to start, maybe trying to be in the right general area. That works surprisingly often and when it doesn't I, and pay closer attention to what I'm selecting, then I pretty much always get through on that next try. This approach mostly fixes the annoying phenomenon where I carefully select the exact right tiles only to be told, "too bad, try again".
