Rating is built on a number of thanks for the posts. For 100% rating is the highest number of thanks for post (leader). Rating the remaining posts is defined as a percentage of the ranking leader. For example, the maximum number of thanks for post #1 = 10. This is 100%. Then post #2 with 5 thanks will have a rating of 50% (10/5). Post #3 with 3 thanks will have a rating of 33,3% (10/3), etc. If the post #1 will receive another thanks (10 +1 = 11), his rating will remain 100% (as leader). Rating post #2 is 45.5% (11/5), rating post #3 is 27.3% (11/3). Position ranking is determined by the number of thanks. Topics rating is made up of the sum of the topic's posts thanks. Forum's rating is made up of the sum of the forum's posts thanks.
