When do you cloak your adwords account?

How long do you wait before cloaking?
How much do you spend before cloaking?
How long you wait to cloak after increasing budget?

OP things you are asking for works differently for everyone. You need to test things to get the idea of days and spending. just run your account for few days like 4 to 5 days or more and spend few dollars and then go for cloaking, it depend on your setup too. Test run everything.
