+Mode could be ruled out immediately. Just consider this: 34% 8MB, 33%
+1.5MB, 33% 1.2MB
+
+I personally believe the median is the most natural and logical choice.
+51% of miners can always force the 49% to follow the simple majority
+choice through a 51% attack. Using median will eliminate the incentive
+to 51% attack due to this reason. The incentive to 51% attack will exist
+when you use any value other than 50-percentile. The further it is from
+50, the bigger the incentive.
+
+Having said that, I don't think it is an absolutely bad idea to use a
+value other than 50-percentile. The exact value is debatable.
+
+However, if you use something other than median, you should make it
+symmetrical. For example, the block size will increase if the
+20-percentile is bigger than the current limit, and the block size will
+decrease if the 80-percentile is smaller than the current limit.
