As far as I know my score hasn't jumped since launch, so I'd say mine is fine. I can't find Teups so I'd call him glitched. dannihm should also be legit, since before yesterday him and I were very close on most of the track lb, and he was barely ahead of me in points.
and easy way to find out if your score is incorrect is to just download either psycads or defoliators spreadsheet and check it yourself. I've done it for myself and my score is correct :-)
