It seems like I misunderstood the documentation on the full hour charge parts, since Google obviously doesn't charge strictly in 0.08$ steps. It changes 0.56$ to 0.54$ so not much difference.
Anyway I've probably found the problem, or should I say bug. After the last request on the backend it waits more or less exactly 5 minutes until it gets the stop signal. Google includes this into the cost calculation, and effectively increases penalty to 20 minutes! With this considered the numbers match. 12*2*(2+5+15) = 0.71$ IMO this is not acceptable and should be fixed. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
