The metric data should usually be stored as one row per conversion event.  The `value` would be the amount of the conversion event.  And then if there are multiple conversion events for a user during an experiment, we sum the values together.

We have a GitHub issue open to allow changing the default SUM behavior when there are multiple conversion events for a user.  That should allow a lot more flexibility in how you store metric data (for example, getting the max or average instead of the sum) <https://github.com/growthbook/growthbook/issues/132>

If I choose the metric type "Count" but the values are different in conversion events, would the framework count all the rows per user or try to sum the "value" field ?

It will sum the `value` field.  If you want it to count the rows instead, you could select `1 as value`

The only real difference between count, revenue, and duration metrics are how we format the values when we display them
