Average Monthly Repeat Logins
This metric measures the average number of returning Residents who logged in during each month of a given quarter. It subtracts the number of Residents who logged in for the first time during a month from the total number of Residents who logged into Second Life at least once in that month and then averages the monthly values for each quarter.

This metric measures the total amount of time spent by Residents logged into Second Life in the month. It’s calculated by summing the combined length of all user sessions for the month.

Exchange Rate
This chart shows each quarter's average exchange rate. This is the weighted average of the rates at which all LindeX transactions executed in the month.
Note that the exchange rate is expressed in L$/USD, meaning larger numbers represent a lower L$ value and smaller numbers represent a higher L$ value. The average rate is calculated by dividing the total L$ exchanged through the LindeX by the total US$ exchanged through the LindeX in the month.
