Hop Absorption

I use whole leaf hops almost every brew and just throw them into the kettle using a stainless scrubby over the dip tube to strain them out. It'd be nice to have a general hops absorption section in either the hop or equipment profile that we can change. I think calculating gallons lost per ounce hops used would be nice. Love the program though! I've been using since the first version and it just keeps getting better!
