I would have worked on 71 if the cost / risk / reward ratio was worth it. It isnt.

Just for fun, lets compare the odds of Puzzle 71 using a 4090 on 0.10$ kw/hr versus buying powerball tickets :

Chance to win powerball 1M prize paying for a 2$ ticket : 0,00000856%
Chance to win Puzzle 71 paying 2$ : 0,00009487%

You're still 10x better off trying your luck on 71 it seems

Hello, I can't send new messages from my DM box and I can't see the incoming messages. I think there is a problem."  I'm glad to hear you'll be taking a detailed look. Since the solution clearly surpasses the 5% threshold you specified, I'm quite confident it meets the criteria you outlined.

That said, if there are any points you'd like to discuss or challenge, I'm more than happy to engage on a technical level.

Looking forward to your response.
