The score progression for each percentile bracket does not match the score advertised when you hover over the placement bars that tell you how many points you get for reaching the next progression. If you hover over an activity bar, where you have only achieved a basic score, it tells you that the next percentile ("Above average") is worth 10 points, when it only gives you 5 when you get there, Likewise, the third tier preview says 50 points (Earn top 30%), when it only actually gives you 10. 4th Tier preview says 100 points (top 10%), it only gives you 50.
