Reminds me of anecdote in Germany after WWI. A lady brings a wheel cart full of money to the bakery to buy bread. Being too cumbersome, she leaves the wheel cart and the money outside and enters the shop to order. When she comes out, she notices the money is still there, but the wheel cart is gone.
If you compound inflation every minute then 1billion% inflation per day is only a little more than 1.1% per minute. If you had 10,000% percent inflation every minute you would have inflation of 10^2880% per day, or in other words, the results of Bushies economic policies.
