Competition Score Calculator — IPMS-Style Judging

Scores your model across 7 weighted criteria, then converts to a percentage of the weighted maximum and assigns a medal grade. This is a heuristic IPMS-style aid, not an official scoresheet: IPMS(UK) and IPMS/USA judge by qualitative elimination (basics first — construction, then finish, then weathering, with accuracy as a tie-breaker) rather than additive points. The numeric weighting here mirrors the only major points-based system, AMPS, which scores Construction highest, Finish and Weathering next, and Degree of Difficulty lowest.

Default Criteria Weights

These are the defaults — every weight is adjustable in Advanced Options, and the breakdown above shows the weights actually applied.

• Construction: ×1.2 — Seams, gaps, alignment, fit
• Surface Finish: ×1.3 — Smoothness, prep quality
• Painting: ×1.3 — Coverage, blending, technique
• Detailing: ×1.0 — Added details, scratch-building
• Accuracy: ×0.8 — Reference adherence, markings
• Presentation: ×0.7 — Display, base, labelling
• Difficulty: ×0.7 — Complexity of subject and scale

Grade bands (default): Gold 90%+, Silver 80–89%, Bronze 70–79%, Commended 60–69%, below 60% is Participant. All four thresholds are configurable in Advanced Options; tiers are auto-clamped so Gold > Silver > Bronze > Commended always holds.
