Khalim Conn-Kowlessar 2c3eb17b96 Slice S0380.33: round synthesized PV kWp to 2 d.p. per RdSAP10 §15 — closes cert 6835 +0.015 SAP residual ... RdSAP10 §15 p.66 (Rounding of data): "kWp for photovoltaics, etc.: 2 d.p." Cert 6835 lodges Photovoltaic Supply as "Proportion of roof area = 40" (no explicit kWp). Per RdSAP10 §11.1 b) p.60 the cascade synthesizes kWp = 0.12 × PV area where PV area is roof_area / cos(35°). For cert 6835: PV area = 36.9 × 0.40 / cos(35°) = 18.0186 m^2 kWp unrounded = 0.12 x 18.0186 = 2.16224 kWp at 2 d.p. = 2.16 (matches worksheet "Cells Peak = 2.16") SAP 10.2 §M1 EPV = 0.8 x kWp x S x ZPV. With the 0.0022 kWp delta the cascade was overstating PV generation by 1.5448 kWh/yr, adding -0.20 GBP to (252) total PV credit, dropping (255) total energy cost by 0.20, lowering ECF and raising SAP by +0.015. Cohort-2 distribution after S0380.31..S0380.33: 35 exact + 3 <=0.07 (was 34 + 4 at S0380.32 HEAD). Cert 6835: +0.014534 -> -4.3e-5.
