Pull request #11107 introduced changes in osu! performance calculation,
related to a scaling coefficient applied to the speed and aim skills.
The coefficient in question was dependent on the approach rate of
a map. During a post-merge review of that PR, it was spotted that
the scaling coefficient for speed also had a 10x buff applied for AR<8,
which could reach magnitudes as large as 80% on AR0, which seems quite
exorbitant. This change was not discussed or mentioned anywhere in the
review process.
Revert back to the old multiplier of 0.01 rather than 0.1 for AR<8. The
negative slope through AR0 to 8 is retained in its previous form.
