-	//      an exemplar will be replaced.
-	//   1) Accept all measurements offered until the configured storage size is
-	//      reached.
-	//   2) Loop:
-	//      a) When the pre-calculate count is reached, replace a random
-	//         existing exemplar with the offered measurement.
-	//      b) Calculate the next random count greater than the existing one
-	//         which will replace another exemplars
-	//
-	// The way a "replacement" count is computed is by looking at `n` number of
-	// independent random numbers each corresponding to an offered measurement.
-	// Of these numbers the smallest `k` (the same size as the storage
-	// capacity) of them are kept as a subset. The maximum value in this
-	// subset, called `w` is used to weight another random number generation
-	// for the next count that will be considered.
-	//
-	// By weighting the next count computation like described, it is able to
-	// perform a uniformly-weighted sampling algorithm based on the number of
-	// samples the reservoir has seen so far. The sampling will "slow down" as
-	// more and more samples are offered so as to reduce a bias towards those
-	// offered just prior to the end of the collection.
-	//
-	// This algorithm is preferred because of its balance of simplicity and
-	// performance. It will compute three random numbers (the bulk of
-	// computation time) for each item that becomes part of the reservoir, but
-	// it does not spend any time on items that do not. In particular it has an
-	// asymptotic runtime of O(k(1 + log(n/k)) where n is the number of
-	// measurements offered and k is the reservoir size.

+// 481–493 (https://dl.acm.org/doi/10.1145/198429.198435).
+//
+// A high-level overview of "Algorithm L":
+//  0. Pre-calculate the random count greater than the storage size when
+//     an exemplar will be replaced.
+//  1. Accept all measurements offered until the configured storage size is
+//     reached.
+//  2. Loop:
+//     a) When the pre-calculate count is reached, replace a random
+//     existing exemplar with the offered measurement.
+//     b) Calculate the next random count greater than the existing one
+//     which will replace another exemplars
+//
+// The way a "replacement" count is computed is by looking at `n` number of
+// independent random numbers each corresponding to an offered measurement.
+// Of these numbers the smallest `k` (the same size as the storage
+// capacity) of them are kept as a subset. The maximum value in this
+// subset, called `w` is used to weight another random number generation
+// for the next count that will be considered.
+//
+// By weighting the next count computation like described, it is able to
+// perform a uniformly-weighted sampling algorithm based on the number of
+// samples the reservoir has seen so far. The sampling will "slow down" as
+// more and more samples are offered so as to reduce a bias towards those
+// offered just prior to the end of the collection.
+//
+// This algorithm is preferred because of its balance of simplicity and
+// performance. It will compute three random numbers (the bulk of
+// computation time) for each item that becomes part of the reservoir, but
+// it does not spend any time on items that do not. In particular it has an
+// asymptotic runtime of O(k(1 + log(n/k))) where n is the number of
+// measurements offered and k is the reservoir size.
+//
+// See https://en.wikipedia.org/wiki/Reservoir_sampling for an overview of
