Depends on the weather and if I'm using energy drinks or food. In winter or through night I'll drink a bottle (750ml) every 3 hours or so. On a summer day it would be more like a bottle per hour. But I'd stretch it out if needed to avoid stops between controls.
On multi-day events I'd drink a bit less as I'd be going slower after the first day, maybe average a bottle per 1.5 hrs.
