Who makes the ACT-SAT conversion?

The conversion chart I see most often is incorrect in my opinion. I received a 28, which was in the 93rd national percentile of the time I took it. On average, a 28 is in the 92nd national percentile. An SAT score of 1980 is in the same percentile, yet the most popular ACT-SAT conversion chart converts a 28 to an 1860. Why is that?
