Reconcile Register Differences Across One Assumed Meter Rollover
A mechanical register can show a smaller number later because it wrapped. Keep that assumption and the register multiplier visible before treating a subtraction as a utility-consumption record.

FIRST-LOAD
HYPOTHESIS / PROTOTYPE — checkout unavailable. Calculation is local. A draft is saved automatically in this browser profile when storage is available; Reset to sample clears it. Optional Pro history stores only five summaries and has its own deletion control. State links encode your inputs and can remain in browser history, clipboard or recipients’ records; share only non-sensitive rows. Optional external AI formatting leaves this device. The required site analytics beacon reports page activity; shared URLs contain encoded inputs. Do not treat an encoded URL as private. The calculator has no input-collection endpoint.
Data note: The dial-rollover stub processes Register code | earlier whole reading | later whole reading | units per register increment locally. Starter/sample selection and Run compute in this tab; no input is sent by the calculator. A local draft may be saved; explicit state-link sharing or optional external AI formatting can disclose inputs. Use non-sensitive labels.
Perspective: Before: a lower later display looked like negative usage. After: the modulus, scale and one-wrap assumption explain the reconstructed increments explicitly.
2 · Read the dial-rollover stub
Single-cycle register arithmetic only, not bill validation or meter-fault diagnosis. Ask the utility to confirm register modulus, multiplier and any reset or replacement; do not use this model when multiple cycles or reverse motion are possible.
Paid layer: dial-rollover stub filing layer
one-time step · the free reading above stays complete
Free tier
- one complete unwatermarked dial-rollover stub run in the app
- three labeled samples and unlimited article-demo calculations
- complete result text and a user-triggered input-state link
What $4 one-time adds
- unlimited subsequent dial-rollover stub app calculations after a local convenience signal
- print the dial-rollover stub with visible assumptions and its safety boundary
- CSV of the displayed common modeled units and row workings; conditional estimate uses your manual-retyping minutes
- five local reading summaries (headline/count/time), not saved full inputs or cross-device backups
HYPOTHESIS / PROTOTYPE: $4 is a proposed one-time price for filing the dial-rollover stub, not a current sales offer. No measured time saving or buyer demand is claimed. The optional manual-retyping baseline above estimates one export’s retyping budget only; it does not change the calculation or guarantee savings.

Boundary and sources
Single-cycle register arithmetic only, not bill validation or meter-fault diagnosis. Ask the utility to confirm register modulus, multiplier and any reset or replacement; do not use this model when multiple cycles or reverse motion are possible.
- Method: When later is at least earlier, subtract directly. Otherwise add modulus minus earlier to later. Multiply the resulting increments by the positive units-per-increment factor. The row states which branch was used, and the summary adds only quantities the reader declares compatible and disjoint. No price or standing charge is calculated.
- All sample records, dates, quantities and labels are invented. No outside policy, contract, rate, clock offset, measurement or accessibility standard is represented as verified.
- Google’s official pricing documentation, fetched 2026-10-01, says AI Studio is free in available regions. Optional formatting may require a Google account; manual local entry requires none. Limits can change and free-tier content may be used to improve products. Do not send private records.

Optional AI formatting, never the calculation
Manual entry completes this dial-rollover stub for free without signup. If available to you, the free AI Studio interface linked in the sources may format fictional or non-sensitive notes; external access may require an account. No API key or AI call is built into this tool. Free-tier content may be used to improve products. Review each cell and transcribe it to the labeled row schema; do not paste the JSON object into the row box.
Format only these fictional or non-sensitive notes for a dial-rollover stub. Return strict JSON shaped as {"rows": [{"label": "string", "cells": ["string", "string", "string"]}], "setting": "string"}. The columns are Register code | earlier whole reading | later whole reading | units per register increment; the setting is Register modulus (one above its largest display). Keep all supplied strings and quantities exactly; do not calculate, infer missing entries, invent dates or add advice. If any required value is missing, return an empty rows array and ask me for it separately. I will verify every cell against my source and manually transcribe rows using vertical bars before running the local calculator.An AI response is not executed, fetched or trusted as a result. Missing values remain questions; the strict local parser checks the rows you actually enter.
