Cocoon Price From Shell Percent
Interpolate a supplied auction shell-percent price schedule and quality multiplier without market-price defaults or out-of-range extrapolation.
Description
An auction price schedule can link measured shell percentage to price.
An auction price schedule can link measured shell percentage to price. Interpolation uses the supplied market schedule, not a built-in price.
Interpolate a supplied auction shell-percent price schedule and quality multiplier without market-price defaults or out-of-range extrapolation.
When to use Cocoon Price From Shell Percent
Use this tool to interpolate a supplied auction shell-percent price schedule and quality multiplier without market-price defaults or out-of-range extrapolation.
Prepare cocoon, larval, leaf or reeling measurements on a consistent batch and moisture basis. Use the declared mass, length and time units.
How to use Cocoon Price From Shell Percent and understand its results
- Prepare cocoon, larval, leaf or reeling measurements on a consistent batch and moisture basis. Use the declared mass, length and time units.
- Enter shellPercentKnots, pricePerKgKnots, measuredShellPercent, qualityMultiplier, lotNetWeightKg using the field table and calculation rules, then run the tool.
- Read calibratedPricePerKg, estimatedLotValue. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| shellPercentKnots | Shell percent knots | list of number | Required |
| pricePerKgKnots | Price per kg knots | list of number | Required |
| measuredShellPercent | Measured shell percent | number | Required |
| qualityMultiplier | Quality multiplier | number | Required |
| lotNetWeightKg | Lot net weight kg | number | Required |
Use increasing shell-percentage knots in [0,100] with aligned nonnegative prices, nonnegative multiplier and lot kg. Query only within the schedule range; return unit price and estimated value.1
price = interpolated shell-percent schedule × quality multiplier Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| calibratedPricePerKg | Calibrated price per kg | number |
| estimatedLotValue | Estimated lot value | number |

}Limitations and assumptions
No extrapolation, market-price default or guaranteed auction outcome is supplied.
Numbers and computed results must be finite; overflow produces an error. Numeric lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Shell Weight Percent SR: Compare matched shell/whole mass ratios on as-received and moisture-corrected dry bases, preserving pooled mass weighting instead of averaging individual percentages. For a complementary task, use Cocoon Grade Sorting Classifier: Classify observed cocoons by a caller descending shell-percent grade schedule with explicit defect/reject codes; no universal trade grade or health certification.
