Can I speed up the auto-dismissal of Notification Center banners?

Question

I like Notification Center, but banners linger a bit too long before auto-dismissing.

I'm aware of the popular two-finger swipe trick to immediately dismiss a banner, but I'm looking for an automated approach. Growl, for example, let you customize how long notifications stayed on the screen, but I don't see a similar option in the Notifications preference pane.

Is it possible to adjust this, like perhaps through a hidden preference?

Although I never usually have any luck finding them, I used MacWorld's guide, "How to find hidden preference settings", and I was able to find the hidden preference:

defaults write com.apple.notificationcenterui bannerTime <SECONDS>

Type the above into Terminal, replacing <seconds> with the number of seconds you want the banner to last for, and press return. Then, log out and log back in to reload Notification Center.

What is the default value? I think there is also a command to erase this setting as well? – cwd Sep 13 '13 at 03:46
@cwd The default is 5 seconds. – prodigitalson Apr 06 '15 at 19:49
