1. A method carried out by a computing system comprising a processor and non-transitory data storage containing instructions executable by the processor for carrying out the method, the method comprising: presenting via a user interface a plurality of data-input fields having an associated default order for user entry of respective values in the respective data-input fields; receiving respective values entered via the user interface in the respective data-input fields; storing a respective current counter value of an incrementing counter in association with receiving each respective entered value; establishing a respective user-confidence level for each of one or more of the respective entered values, wherein each established user-confidence level is set based at least in part on a comparison of the associated default order with a set of one or more of the stored counter values; and outputting one or more of the established user-confidence levels.
