My sheets contain both restrained and released results, with some conditions unlabelled. Although the drawing specifies the dimension, the inspection procedure doesn't clearly define the supports.

Ask quality and the design owner to establish the intended acceptance condition, then group historical results by their documented measurement state to support comparison.

@HenryCarter0960 Same restraint label still doesn't mean comparable. Unknown supports and mixed fixture or process revisions could remain inside those groups.

You're right; I overstated that. Grouping exposes one difference. Keep support conditions, fixture revision and process links visible too, including anything unknown.

Should a fixture revision remain unknown when a colleague remembers a likely version but no record confirms it? We're disagreeing about whether to fill those gaps.

@VictorCarter0968 Keep the revision unconfirmed in the data. A separate note can preserve the recollection as a lead without presenting it as an established fixture reference.

I had a separate bracket job where inferred fixture revisions created an apparent trend. Once the original sheets established the revisions, the trend no longer held.

@BrunoAli0191 If the fixture holds it straight, why isn't that already the result we want?

@JamieAdams0121 The acceptance requirement may apply to the released assembly. A dimension maintained by fixture restraint doesn't establish what that dimension will be once the restraint is removed.

@HenryCarter0960 The drawing owner confirms released inspection on specified reference supports. Quality is putting that condition into the sheet. At least that part won't be guessed.

Useful clarification. It doesn't retroactively tell you how the unlabelled old measurements were taken, though.

My review approach is settled: establish the acceptance condition and use measurements with identifiable conditions. I can take that forward while leaving fixture and process changes dependent on specialist assessment.

You've answered how to frame the records review, with any design or process change still dependent on what the specialists establish.
