Slab Yield Optimizer at 99% target usable-slab yield: a worked example

What does the result look like when target usable-slab yield reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when slab yield optimizer in stone, countertops and engineered surfaces needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Usable slabs cut clean (no defect scrap): 8 count (unchanged)
  • Total slabs entered into cutting: 250 count (unchanged)
  • Target usable-slab yield: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Slab yield optimizer rate = slab yield optimizer count ÷ total slab yield optimizer population × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for slab yield optimizer rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for slab yield optimizer gap to target.
  • At this operating point the engine returns 8 count for slab yield optimizer count.
  • At this operating point the engine returns 250 count for total slab yield optimizer population.

How this compares with the baseline

  • Against the tool's baseline example, where target usable-slab yield sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • A figure at this level is achievable when target usable-slab yield is genuinely sustained, not just peaked for a shift. It treats every slab as equal, so a shop mixing cheap quartz remnants with premium natural stone will see a yield number that hides where the real dollar losses are.
