Default Re: How does Center know?

Well, they generally know that you want to be 30 miles out at 10,000 and 250 to 320 knots.

Or they might know you have a particular crossing restriction as per your arrival and you're getting close to the 3:1 glidepath.

Remember, ATC knows your filed IFR flight plan, your planned airspeed and a little (and I do mean a little) information about the performance of your aircraft.

Speaking of that, my uncle just retired who was a supervisor at Miami Center. They have a madatory age-56 retirement!
