• 1 account per website /APP / Application
• several properties ie subdomains cpanel.quantumwarp.com , demo.quantumwarp.com (you might possibly have a quantumwarp app seperate)
• but 1 account per thing is better because you can do what you want with it including moving the account to another google account. only accounts can be moved and thier permissions controlled

the layout of thes layers of analytics is confusing.
