About the same.
My wife and I make a 12 "cup" pot first thing in the morning. She downs her first large cup within a half hour, then gets a second that lasts her until mid morning, when she stops drinking coffee (or any other caffeinated beverage).
My first cup can easily last two hours, but I continue drinking the stuff all day long. By no later than lunch time, my coffee consumption is augmented by half-sweet iced tea. I'll usually get my last cup around 6 PM, and there will be a bit left in the pot. This has not changed in several decades.
FWIW, my wife has never used nicotine in any form, and nicotine supposedly speeds up the body's metabolism of caffeine. This may explain why she can't sleep if she has caffeine after noon, but I have no trouble at all.
