It may indeed be that people do their turns (much!) faster than every 48 hours, and with quickhost on the game goes as fast as possible when that happens.
Putting it on a 24 hour cycle just makes it harder for people to avoid stales if they are unexpectedly busy,... as far as I can tell, there is no upside.
