All changes made to point modifiers are applied retroactively to all fantasy stats previously earned. Scoring updates the morning following the change.

So, if you are in a Custom League and the commissioner changes the value of a goal from one point to two, all teams find their score in the goals category doubled the following morning.

It is not possible to make a change to your point modifiers and have that change apply only to future games.

At the end of the season, each team's fantasy point total in each category is equal to the raw total they accumulated in that category multiplied by the final point modifier.
