Adjust high CS bonuses after all the distance-time rescaling (#37088)

At this point maybe having a shared small circle bonus in ODHO isn't
even worth it since we have different d/t scalings in all evaluators.
Bonus was made for snap (~d/t^1.65), here it's adjusted to be higher on
agility (~d/t^2) and lower on flow (~d/t). Practically affects like [1
