- The sales of houses on Blackberry Rise, in Portmarnock and in the county, in the five years to 2026, at full market price and second-hand only: a new home sells at the price of new, excluding VAT.
- Each price brought to 2026 by the change in the county's median price, year by year.
- The three medians blended by their sales: this place weighs n / (n + 0.25) for n sales, the locality its share of the rest by its own, the county the remainder. These weights are the ones that came closest to the real prices of 2025.
- The blend, ×0.99 (the median ratio of true to estimated price measured on 2025), gives the figure before your answers.
