Ok. A couple caveats for this parse. First I could not hit 463 accuracy with my gear, so I settled for 466. It took me a bit to get LogRep finally working, however in one of our first two attempts I caught a miss on a small snake, so I added another point and bumped myself up to 467. I then restarted my parse, and was able to get a full 38mins until we killed Twintania. Sorry that the image is absolutely massive, but people requested individual ability numbers. Here are the results:
This certainly doesn't confirm anything, but it suggests it may be somewhere in the 467 range since I did get a miss at 466. It would be nice if some other people could parse around 467 and we'll see if we can lock this down, I can't go again for another week.
