Claim:
1. A method for monitoring yield while harvesting grain with a harvester including axles, the method comprising: with a mass flow rate sensor disposed to measure a mass flow rate of grain in the harvester, generating a flow rate signal related to a grain flow rate within the harvester as carried by the axles; generating a weight signal related to a weight of the entire harvester; monitoring a data quality criterion associated with said weight signal; calibrating said flow rate signal with said weight signal in order to generate a calibrated flow rate signal; while harvesting grain, estimating yield based on said calibrated flow rate signal; determining whether said data quality criterion exceeds a trusted data threshold; and upon determining that said data quality criterion exceeds said trusted data threshold, discontinuing calibrating said flow rate signal with said weight signal.
