This seems right as it looks the results were explained this way to provide a competitive hook to promote the site....hence the monthly turnover of results allows you to improve even tho' the disclaimer points out the results would be inaccurate 'cos you would then be learning.

It's marketing...just enough sense to hold your casual attention but not enough to stand up to scrutiny.

The only accurate comparasion (& the data he's after) would be against the results of everyone who ever took the test once with the results updated for everyone after each test. As you can take this test twice (after all he needs hits to fund his research) this database should have been rendered useless for that purpose except people who insist on ignoring the disclaimer are redirected by the 1st screen...

Since the %s so far seem to reflect straight scores out of 15 (don't they?) the 'comparasion' is designed to get those 2nd hits....marketing.
