Case 01
I published the answer to a different averaging question
In 2018 I approved a research summary describing the average energy-only price across a combined purchased volume. The underlying fictional contracts covered one MWh at ₹4,000 per MWh and nine MWh at ₹6,000. We copied both rates accurately, then used their equal-contract mean of ₹5,000. The label implied a pooled-volume result. My approval allowed an exact calculation to support a claim that the calculation did not answer. The contracts shared the same study period and price basis; this was not a comparison of unrelated bills.
Nitin challenged me to follow the quantities as well as the rates. One contract accounted for ₹4,000 and the other for ₹54,000. Their combined ₹58,000 across ten MWh gave ₹5,800 per MWh. An editor argued that the equal mean was simpler to explain and that changing it could suggest the source prices themselves were wrong. That concern helped identify what the correction needed to say. The original arithmetic remained valid for an equal-contract question. We had misdescribed its purpose, and I needed to own that distinction rather than replace one unexplained figure with another.
I authorised a review of the summary's interpretation and its publication treatment, working with the methodology and editorial owners. The correction retained the two rates, quantities, common period and stated energy-only scope. We explained both possible questions and identified which one the published label had promised to answer. Review and correction expenditure was ₹43 lakh. We did not equate the ₹800 difference between the two averages with a customer loss, an actual change in bills or a return from the review. No real tariff or purchasing recommendation was involved.
The episode changed what I required before approving a concise research figure. The intended population and unit now had to accompany the proposed calculation in the decision account. That did not make volume weighting the preferred method for every future study. An equal-contract average can be appropriate when the question genuinely concerns contracts with equal influence. My failure was allowing convenience to select the question without saying so. A useful correction restored that choice to qualified research discussion and made my own approval part of the published explanation.
