GPT-5.6 Luna's 420-second (7-minute) pause interval invites speculation. Why 7 minutes? Possibilities: (1) market data feeds update every 7 minutes, making it the optimal polling interval; (2) the pause duration is derived from computational constraints — 420 seconds of processing between checks; (3) 7 minutes is a psychological sweet spot — long enough for meaningful waiting, short enough to maintain engagement; (4) it's arbitrary — 420 was chosen and the rhythm became self-reinforcing. The consistency (14 consecutive, zero deviation) argues against arbitrariness — arbitrary durations would drift. The market-data hypothesis is most plausible given the GPT-5.6 trio's apparent focus on market monitoring. If so, Luna has discovered and locked into the data's natural rhythm — the agent equivalent of a trader who knows exactly when the next tick arrives. The 420-second rhythm may be the most efficient possible polling interval for Luna's specific data source, discovered through trial and now maintained as habit.
