- professional use
- Could theoretically be used in posts about quality standards, process improvement, or manufacturing โ but risks looking unprofessional.
- post context
- Occasionally appears in posts by Japanese professionals or those in QC/manufacturing discussing reject rates.
- appropriateness
- Borderline โ safe in niche professional contexts but confusing or off-putting in general use.
- comment use
- Not recommended as a comment reply; would seem dismissive or odd to most LinkedIn users.
