How’s your IG follow back %

So I've been running IZ since my FL limits nosedived in August. When you run IZ they give you a follow back ratio per account that you scrap, then an average for all accounts. I have around 225 accounts that I'm going to scrap in the long term. Anyways, just wanted to know what a good follow back average would be? I'm sitting around 9% overall, just wanted o see how everyone else is doing.
