Merge overlapping vaping records without counting the same event twice

Start with the question the combined record must answer

Perhaps you want to know which situations appeared repeatedly, rather than calculate a precise daily total. That distinction matters: overlapping notes may still reveal useful context even when the count cannot be reconstructed. Decide the question before changing either record.

Write down the period covered by each source and its unit. One entry might represent a session, another a puff, and a handwritten daily figure might already include events recorded on the phone. Matching dates alone does not establish that the numbers can be added. No Vape describes puff tracking and progress; it does not establish how a separate notebook was compiled.

Keep an untouched copy and make a reconciliation sheet

Use a separate sheet with four columns: source entry, possible match, reason for the match, and decision. Retain each original in a place appropriate for private information. This is an editorial recordkeeping exercise, not an import or duplicate-removal function promised by any app.

For a hypothetical example, a paper note says “after lunch, three puffs,” and your phone record describes that same observed event. If you remember entering the event in both places, mark the pair as one known event with two records. If all you have are two daily totals, leave the relationship unresolved rather than inventing individual events to make them agree.

Distinguish a known match from a plausible guess

A shared time or similar description can help you investigate, but does not prove a duplicate. Someone may record two separate events close together, or enter an earlier observation later. Check what the timestamp means if the service explains it. Preserve uncertainty when it does not.

Do not average incompatible totals as a shortcut. Averaging does not recover the missing information about overlap. A note such as “both sources cover Tuesday; combined total not established” is more accurate. If you later find a reliable clarification, record the correction and its reason instead of silently rewriting the history.

End the overlap prospectively

Choose one primary counting route for new observations and give the other a different purpose, such as describing context. A small trial with your next real entry can show whether the arrangement is clear. You do not have to reconstruct every old day before resuming your current plan.

When sharing a summary, include the overlap limitation beside the affected period. Keep the original sources available if you choose to discuss them with a professional. The sheet improves transparency; it cannot recover forgotten use, measure nicotine exposure, or demonstrate a health outcome. Its value is a record you can explain without pretending every number is exact.
