SQL PERCENTILE_CONT over daily-best per-product-per-day observed in-stock prices
6 frozen months for .40 S&W, March 2026 to August 2026. Each month is computed on its own from that month's observations and then locked; it is a level, not a change from the month before. No calendar month between them is missing a published snapshot. Points are shown unconnected: the set of tracked retailers behind each month was not comparable to the month before it, so no line is drawn between them.
