Google Calendar Sync Frequency

Does Nuevasync support push calendar syncing? E.g. I have activesync set to "sync as Items arrive", does that sync new items as they are input on the google calendar as soon as they are input?

NuevaSync supports push sync, however there is no way for is to get notification of calendar or contact changes from Google in real time, so the service polls for changes every few minutes. When it does find a change, it pushes the update to the phone. Data sources that do support real-time change notification (IMAP Email for example) push immediately.
