Alpha % loss for stored hops

[bobbrews]

I bought some Columbus 17.1% leaf hops a year ago. Does anyone know the average alpha % loss over the course of a year for leaf hops kept in a ziploc bag in the freezer? These are not vacu-sealed. It's a simple plastic freezer bag.

:rockin: Still good though use them for bittering additions, the aroma should have gone down a lot to.
