On the "usage history" page with the vertical list of usage values, where you land if you navigate to app engine --> quotas --> view usage history in the dev. console, there is an information label on top saying: "These costs are estimates based on App Engine list prices." Estimates may be wrong to some extent, as they are what they are named: only estimates, in contrast to guaranteed and double-checked values. In your case the estimates are mostly 0.01. In all cases, these values are provided for orientation and best-effort basis, just to provide an estimate. They are not meant to be compared with final values.
