**Sum**: Adds up all data entries within the period**Sum - Ignore Period**: Adds all data entries ever stored**Sum - Difference:**Takes the total of data entries for this score period and subtracts the total of the previous period**Latest**: The most recent data entry within the period**Latest - Ignore Period**: Takes the most recent data entry ever**Latest - Difference**: Takes the difference between the most recent data entry of this period and the last data entry of the previous period**Lowest Score in Period**: Takes the lowest data entry in period (Min)**Highest Score in Period**: Takes the highest data entry in the period (Max)**Average Score in Period:**takes the average of all data entries in the period.

There is also a special case score method called **Linked Metric** which is explained below.

These score methods can also be shown visually as below:

# Sum

*Sum*will sum all scores during the scoring period (Default)

# Sum - ignore period

*Sum - ignore period -*will sum all data entries ever stored

# Sum - difference

*Sum - Difference -*will return the difference between the sum of data entries for this period with the sum of data entries for the previous period

# Latest

*Latest*will use the most recent score entry in the current period

# Latest - ignore period

*Latest - ignore period*will use the most recent score entry no matter when it was scored

# Latest - difference

*Latest - Difference*will take the difference between the last score entry of the previous period and the most recent score entry for the current period.

# Highest Score in Period

*Highest Score in Period*will take only the highest score as the entry for the period.

# Lowest Score in Period

*Lowest Score in Period*will take only the lowest score as the entry for the period.

# Average Score in Period

*Average Score in Period*will take the mean of all data entries for the period

Note that the "ignore period" score methods also affects the 92 day data entry deletion rule and will mean that data entries are not deleted after the 92 day data storage period expires.

**Linked Metric**

Linked Metric solves a problem when using Wufoo to bring in multiple scores for a single player in the same period. When a player can submit several scores via wufoo at different times then the score algorithm would take their best score (max or min) on the primary metric. But if there is secondary data being sent (maybe the primary metric was number of hits and the secondary metric was the time it took to achieve it) then in order to tell Rise to follow the primary metric choice then Linked Metric does this - it will take the secondary data from the same wufoo entry as the primary metric.
