SQL PERCENTILE_CONT over daily-best per-product-per-day observed in-stock prices
3 frozen months for .357 SIG, March 2026 to October 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. Months between them without a published snapshot are left empty rather than estimated: April 2026, May 2026, June 2026, July 2026, and August 2026. 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.
Each month shows two medians: range / practice loads (FMJ-class) and premium / defensive loads (hollow points, hunting and match). A single median across both would depend on how many of each kind the tracked retailers listed that month, so it is not shown. A dash means that kind had fewer than 15 observations in the month, or the month has no split. Samples counts every observation in the month, including loads in neither kind.
