[BTTF2] How does Biff know how the time machine works in BTTF2 as he’s a moron..?

In ‘Back to the Future 2’ Biff steals the Delorean and travels back to give over the Almanac, seeing he’s the classic goof bad guy how does he operate the time machine with no formal training or knowledge of its speed requirements etc..?

Old biff flies off with the time machine, he doesn't time travel immediately.  He took as much time as needed to learn how it works. He could have spent a week or a month or an hour  figuring out, as his future self brought the time machine back to the moment earlier Biff flew off.

All he needed to know in a hurry was how to steal a car.
