Ok, after re-reading your first post and last, I think I understand what you mean. If you have it collecting at 1 minute interval, and set your alert definition to fire every 2 times in 10 minutes, then you'll get an alert every 2 minutes. The 10 minutes sets a boundary for how long to allow for 2 collections to match the condition, but is not an exclusionary period. It doesn't mean that it'll only fire 1 time in 10 minutes, it means that every time you have 2 matches within a 10 minute window, an alert will fire.
If you want to restrict the number of alerts you receive, you should do it through the escalation scheme. Select "Suppress Alerts" for 10 minutes. That way every time an alert fires, the app will wait 10 minutes before firing another one.
