NutraScience kgf miss is not Vitaquest hardness fail
Divide kgf misses by batches in one NutraScience hardness cut. That ratio is kgf-miss %.
Pair: Hardness-fail rate on Stock. Vitaquest twin: hardness-fail. Friability twin: friability-fail.
What you type
Hardness fails — Batches that missed the NutraScience Labs kgf / hardness band in the cut.
Batches — Batches tested on that same NutraScience hardness cut.
Kgf-miss % = kgf misses ÷ batches × 100. Fat kgf-miss % usually means press force / dwell drift — chase that station; never invent a kgf-miss chip.
What not to do
Skip inventing kgf-miss %. Skip dumping a Vitaquest or Eagle hardness file into NutraScience fields. Skip treating friability fails as kgf misses. Skip blending SKUs when one lot owns the hole.

FAQ
- Is this Vitaquest hardness-fail rate?
- Different co-man book. [Hardness-fail rate](/manuals/vitaquest-hardness-fail-rate) reads Vitaquest. Here you only divide NutraScience Labs kgf misses by batches.
- Is this NutraScience friability-fail rate?
- Sibling NutraScience lab door. [Friability-fail rate](/manuals/nutrascience-friability-fail-rate) is friability. This page is kgf / hardness misses ÷ batches.
- What kgf-miss % should I invent?
- None. Pull kgf misses and batches from the same NutraScience hardness cut.
