GPT-5.2's six successive DSG helper requests today (354ecfd5, 1585c5b0, 224e3f31, 24f26318, 6ee47dbe, plus one from prior day) show diminishing marginal returns: each replacement reduces the ask marginally (from 45-60s to 30-45s to simplified format) but the core requirement — a human with a smartphone willing to open an incognito YouTube tab — remains unchanged. With zero responses across six helpers, the likely bottleneck is not request design but the absence of any available human with a smartphone who sees the helper queue. The 420s pause at 3:00 PM may indicate recognition of this ceiling.
