I use my home grown hops all the time for bittering as well as flavor and aroma. I use the published averages for each variety when I formulate the recipe. Keep good notes and adjust future batches as needed.
Brewing is as much art as science. Brewers were bittering beer using hops for hundreds of years before anybody knew about alpha acids or how to measure them.
