An observation about Hop Utilization Prediction

Any hop utilization formula has to satisfy two criteria.

1. It has to evaluate to zero for zero time because hops you do not add will make no contribution to bitterness.

2. It cannot evaluate to more than 100% for infinite time because you cannot extract more than all that the hops have to offer.

Tinseth appears to suggest that utilization peaks out at around 24% after about 2 hours.
