What It Is
SPS is a straightforward projection methodology that uses a weighted average of recent seasons' performance to project future production. It typically applies declining weights to older seasons (e.g., 60/30/10 for three recent years).
APEX Rationale
Not used in APEX as a scored component. However, APEX's V2 Roadmap includes a multi-year weighted average toggle (60/30/10 weighting of prior seasons as an optional input mode) — this is essentially the SPS framework applied to stabilize current-season scores, not as a projection tool.
