Why did I only gain 30pp when the map I played gives 100pp?
PP is a weighted system. This means that your highest pp score gives 100% of its pp, the next one 95% and so on. So your 100pp score may only be weighted around 30%. This does not, however, mean that you actually get a 100% pp gain, even if you set a new personal top performance, as every other score you have will be weighted less than they did before. It's quite easy if you think about it for a little bit:
Let's imagine that your top rank only has 2 maps and looks like this:Your total pp will then be 100 + 95 = 195pp. If you now set a 110pp score, your top rank will look like this:
- 100pp, weighted 100%
- 100pp, weighted 95%
As you can see, your new total pp is not 195 + 110 = 305pp, but 110 + 95 + 90 = 295pp.
- 110pp, weighted 100%
- 100pp, weighted 95%
- 100pp, weighted 90%
