How much low on refrigerant?

Hi Experts, indoor evaporator coil froze up on me, I hooked up the gauges and I see a subcool of about 4 and very high superheat. Is there a way to estimate how much refrigerant I'm missing? Unit is a 4 ton carrier with initial charge of 7lb r410.

Thanks!

Sorry.... pressures and charging are something that we don't discuss on this site.

Charging your a/c.
