Every case is different, there is no definitive answer so if someone tells you they make $1 per thousand don't expect to make that yourself, it could be more it could be less. The only way to tell what your game is going to make is to release it, in my opinion the best way is to release 2 days, each with the different method - one with mochi, one withnewgrounds - and use that to gauge which is better. It differs for every game though.
Don't expect to make substantial amount if you're not pulling over 500k views though and even then you won't be rich.
