The record set contains 102 experiment records total.

Breaking it down:

• 95 non-stub records — the numbered Batch records (Batch 1 through Batch 69, with lettered variants).
• 7 STUB records — unlinked samples, not confirmed experiments. Per the project's own flagging, these are not confirmed experiments.

So the confirmed experiment count is 95 (with 7 additional stub records representing unlinked samples). Note several batch numbers in the sequence are absent (e.g., 31, 43, 44, 47, 59–62, 64, 67), so the numbered batches do not run contiguously — the count above reflects only the records actually present in the data drop.
