Exhibit Condition Philatelic Significance Weighted Score

Aggregate independently assessed exhibit condition/significance scores under caller weights; unknown criteria remain explicit. Caller independently verifies observations, reference edition, units and applicability; not a grading-service certificate, authentication, conservation treatment, actual market price or legal/insurance entitlement.

Description

An exhibit significance score can combine criteria with explicitly chosen weights.

An exhibit significance score can combine criteria with explicitly chosen weights.1

This calculator averages only known weighted observations and separately reports how much of the total weight was assessed.

When to use Exhibit Condition Philatelic Significance Weighted Score

Use this tool when you need to summarize the supplied collecting records or matched observations. Prepare independently verified observations, reference edition/context, and matching units or currency basis.

How to use Exhibit Condition Philatelic Significance Weighted Score and understand its results

  1. Prepare independently verified observations, reference edition/context, and matching units or currency basis.
  2. Enter callerCriterionScores, callerCriterionWeights, scoreKnownFlags, following the field table and calculation rules below, then run the tool.
  3. Read knownWeightedScore, knownWeightFraction, unknownIndices. For result objects, inspect the nested output fields below, including any missing evidence or selected indices.
  4. Correct any input issues and run again. Before using a successful result, review its units, signs, evidence coverage, and stated model or reference assumptions.

scoreKnownFlagsScore known flags; binary 1 means assessed and 0 means unknown.list of numberRequired

Require nonempty aligned finite scores, nonnegative weights, and binary known flags, with positive total weight. Divide the known weighted score sum by known weight; if known weight is zero, return a zero placeholder. Return knownWeightFraction and unknownIndices so the placeholder cannot be mistaken for a measured score.

knownScore=knownWeight>0?Σs_i w_i k_i/Σw_i k_i:0; coverage=Σw_i k_i/Σw_i

Read these symbols with the field meanings and branch or reference rules above.

Limitations and assumptions

Observations, reference edition, and applicability are independently supplied. Arithmetic and reference summaries do not provide authentication, a certified grade, or an actual market price.

Missing required fields, unknown fields, wrong types, and violated calculation rules return input issues. Numeric values must be finite; nonfinite numeric outputs are rejected. Arrays must be dense, with no missing cells. Numeric lists allow at most 10000 entries, subject to smaller tool-specific bounds above.

Alternative or Complementary methods

For a related task, use Exhibit Treatment Plan Coverage Percent Scorer: Exhibit coverage can be weighted by the relative importance of specified treatment areas. This scorer separates witnessed coverage from the weight of unassessed areas, so unknown entries do not count as covered. For a complementary step, use FIP Medal Threshold Points Mapper (95-60): Exhibition medal thresholds depend on the applicable class, rules, and reference period. This mapper finds supplied half-open score bands and retains every matching medal label, including overlapping references.
