How Long Does It Take to Work Through an ADR Line?

If it takes more than five or six is that too many? Well I mean beginners are going to take a few times because they're still learning sync and sounding natural. If you make an actor read a line more than five times you're not going to get anything better. It's different with Foley because they may not have found the right sound yet, depending on how they operate. So at a certain point you're going to sense whether someone's frustrated and you just need to go on.
