estimated_execution_count

Same as count but potentially scaled upwards if the server was only performing field-level instrumentation on a sampling of operations. For example, if the server randomly instruments 1% of requests for this operation, this number will be 100 times greater than observed_execution_count. (When aggregating a Trace into FieldStats, this number goes up by the trace's field_execution_weight for each observed field execution, while observed_execution_count above goes up by 1.)
