I was just wondering the same. Ran's last post in each rating thread for season 4 has the following:
Ep 1 "Two swords" - 626 votes, 8.16 average. 8 median, 8.28 normalized average.
Ep 2 "The Lion and the Rose" - 545 votes in, average of 8.33, median of 9, normalized average of 8.48
Ep 3 "Breaker of Chains" - 549 votes in, 6.97 average, 8 median, 7.08 normalized average
Ep 4 "Oathkeeper" - 614 votes, 7.66 average, 9 median, 7.86 normalized average.
ETA: Of course we still need all the UK etc. viewers to vote for this episode. :)
