Prevent estimated earnings counter from ever decreasing unexpectedly

[Miyayes]

Description

Lots of users report the estimated earnings counter decreasing suddenly. Many users watch the estimated earnings counter like hawks, so any non-monotonically increasing changes will immediately make them distrustful and angry. Even if the estimated earnings counter resolves itself after awhile (e.g., a browser restart or after an hour or so), it should not decrease in this way.

Is it the case that the estimated earnings can never be over-calculated (such that drops in the estimated earnings amount are actually required for accuracy)? If so, then we should be able to prevent it from ever decreasing unexpectedly.
