Why did my score change?

Your score moves whenever the pattern of your entries changes. Common reasons:

You logged a new entry: every new entry shifts the ratio of positive to negative tags.

Recent entries are weighted heavier: entries from the last 7 days count double. So if a recent entry is negative and most of your older entries are positive, the score will drop more than you might expect, because the recent one is being weighted as if it were two negatives.

An older entry aged out of the window: the score only looks at the last 30 days. If a strongly positive entry was logged 31 days ago, it just dropped out, and the score recalculates without it.

You corrected a tag: tapping a tag to change it from positive to negative (or vice versa) will recalculate the score.

You deleted an entry: removing an entry rebalances the math.

If the score moved and you cannot tell why, open the connection and look at recent entries. The shift will almost always trace back to what you logged most recently.
