 ### Sampling Method
@@ -51,10 +69,8 @@ This dataset was created using **reservoir sampling**, which ensures:
 The sampling algorithm:
 1. Streams through HuggingFaceFW/finewiki without downloading
 2. Uses GPT-2 tokenizer to count tokens per document
-3. Maintains a reservoir of documents until target token count
-4. For each new document, replaces reservoir items with probability k/n
-   - k = reservoir size, n = total documents seen
-5. Guarantees uniform random sample across entire dataset
+3. Maintains a reservoir of documents using standard reservoir sampling
+4. Stops when target token count is reached
