These days, the data comes from high-energy interactions, and often involves highly improbable events. If you don't already know what to look for, you will have to slow down and analyze every event. If you do know what to look for, you can dial up the frequency of events tremendously, paying close attention only to the ones that surprise you in some way. This cuts observation times from well beyond human lifespans, to a matter of a year or two. It makes them practical.
