158.9 tCO2ebetween 114.4 and 220.7 about 90% of the time (P5 to P95) The median is the middle estimate. The band runs from P5 to P95: the true value falls inside it about 90% of the time.Measured and confirmed (V3)A tier says how the evidence behind a figure was obtained. It is evidence quality, not assurance.

Why this tier

Measured and confirmed (V3): regional proxy limits evidence quality.

Capped because a regional proxy factor is used. Regional evidence is limited; band widened

How to move this up

Nothing more is needed below assurance. Only a practitioner’s signed report goes further.

Who to check it with

O. Haddad (synthetic), site engineer at Ochrefield Tower.

What could we add

A supplier statement or a meter reading for the same weeks.

Monthly change review

Not known, because monthly results are not supplied.

The engine has supplied a quarterly figure, not monthly values or a paired difference band. A quarter cannot be split into invented months.

No monthly jump is asserted. This is not clearance to file; existing findings and close blockers still apply.
