Reconcile a source-labelled pool length, target distance, explicit count convention, complete lengths and any partial final distance.
Choose your path
Reconcile one source-labelled pool length and target distance with an explicit one-way-length or down-and-back-pair convention, preserving any partial final length and comparing an independent same-record count.
Verify target-distance count arithmetic without turning the worksheet into facility or event certification.
Name the published facility or event sheet, retain the stated m/yd pool length, define one count exactly and compare the reproduced count with an independent worksheet.
Can identify an arithmetic mismatch while dimensions, markings, configuration and official status remain with responsible records and rules.
Avoid rounding an incomplete wall-to-wall segment into a completed length or pair.
Enter a reviewed 110 m target and 25 m pool, select one-way lengths, then inspect four complete lengths plus the exact 10 m partial distance before deliberate retention.
The record preserves the partial finish and never silently reports four or five completed lengths as the whole target.
Keep source units, course context and counting conventions from being silently combined.
Reconcile a 1650 yd / 25 yd record independently, change the count convention deliberately and retain the source unit with every intermediate.
Receives auditable count arithmetic without a metre-performance conversion, training claim or causal explanation.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.

Reconcile pace per 100 for one completed, source-labelled swim distance and elapsed-time record without converting course performance or prescribing training.

Copy the convention stated by the source. The word lap is not treated as having one universal meaning, so the selected convention and its source description remain visible with the result.
Count distance = pool length for a one-way length, or 2 × pool length for a down-and-back pairA target that does not end at a wall is reported as complete one-way lengths plus the exact distance into the next length. The worksheet does not round the target upward or claim that the partial segment was completed.
Complete lengths = floor(target ÷ pool length); partial distance = target − complete lengths × pool lengthCompare only counts prepared from the identical recorded unit, pool length, target distance and convention. A zero difference confirms arithmetic agreement, not pool certification, event validity, completed distance, training suitability or safety.
Difference = reproduced exact count − independent same-record countUpdated: August 2026
Copy a reviewed 25 m pool record and a 2000 m target, define one count as a down-and-back pair, and compare the reproduced 40-pair result with an independent worksheet without certifying the facility.
For a reviewed 110 m scenario in a 25 m pool, retain four complete one-way lengths plus 10 m into the next length instead of displaying only four lengths or rounding up to five.
Reconcile a published 1650 yd / 25 yd record as 66 one-way lengths or 33 down-and-back pairs while leaving any metre record as a separate source scenario rather than converting performance.
Use one source-labelled pool-distance record at a time. Keep metres and yards separate, state whether one recorded count means a one-way length or a down-and-back pair, and preserve any partial final length instead of rounding it into a completed wall-to-wall length. The worksheet checks arithmetic only; the original facility, event or completed-count record owns dimensions, completion and official status.
