It seems like the algorithm may not have been updated. For example, it only allows you to enter a max SAT score of 800, but then on the "chances" it says the average score is 1530 and you need to improve your score... even when I enter 800 which is the max.
The profile has you input both sections of the SAT separately. 800 is the max for each section.
Your 2 section tests have a max score of 800 so when combined it give the out of 1600 score
