A SR:PR (Site Record:Personal Record) ratio is equivalent to (SR / player's score) for a particular track. This
ratio is 1.0000 when the player holds the SR. The further the score from the SR, the smaller the ratio
(ratios closer to 1 are better). This chart shows the averages of these ratios.
Both the SRPR and AF scores reward consistency - a single weak score can negatively affect you in a big
way. These scores fluctuate constantly, since they change when you overtake someone (or someone overtakes
you) in any of the 36 charts. The ARR score is different to the two indicators above, since it will not
change unless you beat a new standard. This means that other players settings new PRs will not affect your
score, but will probably affect your position on in this table. Certain player titles may be awarded based
on your ARR score.
Your SR:PR ratio will improve when you get a PR (unless you improve on your own SR, in which case it stays same...
but everyone else drops). Your ratio will worsen only when somebody sets a new SR.
