How Blk 273D Compassvale Link scores 80/100
Every number on this block’s page, opened up. Below is each pillar, each component inside it, the exact walk time or distance we measured, and the weighted arithmetic that rolls it up — so you can check the score yourself. Nothing here is hand-tuned; the same weights apply to all ~12,800 blocks.
← Back to Blk 273D Compassvale LinkA closer amenity scores higher on a straight-line decay: full marks at or under the “full” threshold, zero at or beyond “zero”, and a straight line between. Remaining lease uses the mirror growth curve. A component with nothing in range scores 0 — never a fabricated amenity. See the full methodology for the formulas and data sources.

Each pillar, component by component
Sub-scores are frozen in the current snapshot (2026-11); the measured input beside each is the amenity that produced it.
Transport
Everyday mobility. The nearest MRT/LRT exit dominates because it sets your reach across the island; the nearest bus stop covers the last mile; a small slice credits a planned-but-unopened station nearby.
| Component | What we measured here | Sub-score | Weight | Contribution |
|---|---|---|---|---|
MRT / LRT Walk minutes to the nearest rail exit | Buangkok Mrt Station · 2.9 min walk decay(2.9, 4, 20) = 100 | 100.0 | 55% | 55.0 |
Bus stop Walk minutes to the nearest bus stop | Bus Stop · 2.2 min walk decay(2.2, 2, 10) = 97.5 | 97.5 | 35% | 34.1 |
Planned rail Straight-line metres to the nearest MP2025 planned station | Defu (planned) · 2486 m decay(2486, 400, 1600) = 0 | 0.0 | 10% | 0.0 |
Transport = 0.55×100 + 0.35×97.5 + 0.10×0 = 89.1 ✓ matches the 89.1 shown
Food
Access to cooked food, blending hawker centres with the denser layer of NEA-licensed eateries. “Nearest” rewards proximity, “choice” rewards density, hygiene rewards quality.
| Component | What we measured here | Sub-score | Weight | Contribution |
|---|---|---|---|---|
Nearest hawker Walk minutes to the nearest hawker centre | Buangkok Hawker Centre · 5.5 min walk decay(5.5, 5, 25) = 97.5 | 97.5 | 30% | 29.2 |

EV charging
How practical it is to own an EV. Proximity matters sharply because you charge where you park; the second component rewards having several chargers in range.
| Component | What we measured here | Sub-score | Weight | Contribution |
|---|---|---|---|---|
Nearest charger Walk minutes to the nearest EV charger | Blk 277 Compassvale Link Aspella · 4.1 min walk decay(4.1, 3, 15) = 90.8 | 90.8 | 70% | 63.6 |

Who-it-suits scores
Each persona score re-weights the same pillars for a different household. The base is a weighted average of the pillar scores above; four personas then get a small, bounded nudge (≤ ±3) if the planning area’s census mix fits them.
| Persona | Pillar-weighted base | Demographic fit | Final |
|---|---|---|---|
| Young Families | 83.5 | +2.7 | 86.2 |
| Seniors | 76.1 | -2.4 | 73.7 |
| Renters | 75.0 | -0.1 | 74.9 |
| EV Owners | 82.6 | -0.5 | 82.1 |
0.55 × overall (80) + 0.25 × resale momentum (81) + 0.20 × value (84) = 81.2 ✓ matches 81.1
Momentum is the subzone’s resale price-per-sq-ft trend as a 0–100 percentile against all subzones.
