@storm5510 I think what you write sums it up exactly. At least that's my understanding too. I compare it in my mind with the "kilowatt hour" as a measure of consumption of electricity.
@M344587487 Indeed. But I was running a machine on GIMPS with a processor speed of about 1 GHz right up until it packed up in November 2017. By the end it was taking about 5-6 months (running about a third of the time - I didn't leave it on 24 hours a day) to do a double check in the 40-45 million exponent range which the project had reached by then. My machine was occasionally the subject of a certain amount of hilarity here.
