- Largest supplied pressure by condition
- T1: 200; T2: 200
- Maximum-minus-minimum as share of condition maximum (%)
- T1: 10; T2: 20
- Lowest-reading cylinder IDs by condition
- T1: C1; T2: C1

Calculation method
Calculation method
Smallest supplied pressure by condition
Group only matching supplied test-condition labels, then take minimum.
Largest supplied pressure by condition
Take maximum within each condition.
Maximum-minus-minimum as share of condition maximum (%)
100×(max−min)/max; undefined if every reading in a condition is zero.
Lowest-reading cylinder IDs by condition
List all cylinders tied for the condition minimum, without diagnosing causes.

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- A descriptive grouped pressure-reading comparison, not an engine-condition or maintenance diagnosis. Test conditions, pressure units, specifications and acceptance thresholds are not inferred or mixed across labels.
