The weights
| Dimension | Weight | Definition | Data source |
|---|---|---|---|
| Person Capacity | 16% | This dimension reads person capacity straight from the listing — higher listed values score better, and an absent value stays neutral. | Person Capacity |
| Jet Count | 15% | Published listings put jet count between 11 to 73; higher numbers score better, and a missing value stays neutral. | Jet Count |
| Pump Horsepower | 13% | The pump score maps the listed value directly, so higher listed values score better; a missing entry holds neutral. | Pump |
| Heater Power | 12% | This dimension reads heater kw straight from the listing — higher listed values score better, and an absent value stays neutral. | Heater Kw |
| Insulation | 12% | The insulation type scale runs from Reflective to Full Foam; entries nearer Full Foam earn the most credit, while unlisted ones stay neutral. | Insulation Type |
| Shell Material | 10% | Scoring shell material follows the Inflatable-through-Acrylic ladder where the top rungs win the highest marks, and a missing entry holds neutral. | Shell Material |
| Water Capacity | 9% | This dimension reads water capacity straight from the listing — higher listed values score better, and an absent value stays neutral. | Water Capacity |
| Ozone Or UV Purification | 8% | This dimension checks whether ozone or uv purification is listed; yes earns full credit, while no or missing earns zero. | Ozone Or Uv Purification |
| ENERGY STAR Certified | 5% | Listed energy star certified is a presence check — a yes takes full credit, and a no or absent value scores zero. | Energy Star Certified |

What the score bands mean
Score bands80+ strong60–79 solidBelow 60 limited fit
- 80+: strong marks on the heaviest dimensions with few weak lines in the listed specs.

Source hierarchy
Published manufacturer specifications rank first, dated retailer records second; marketing claims without a checkable figure are excluded from scoring. Missing values never earn invented numbers; they are labeled “not listed - neutral 50” and take the neutral 50 grade the weight definitions describe.
