Has any of those 3700 files helped you solve any puzzle (or at least help you make any progress whatsoever)?

In back testing I have come within 0.001 % +/-, but we all know how much space that amount still is to cover.

I do, it's very very small, do-able in a day or less (costs would be less than 100$). So I think the answer of my question was a no.

I find it hard (impossible actually) to believe that you can solve within a 0.001% error, but haven't snatched anything, it would have taken just a few hours or days even for 71. Looking in retrospective, anything can be solved without errors, but this has zero impact on the future. But if you manage to prove that you have that kind of a error margin with any set of random data (any other set of 70 fixed samples), you'd sit in the Hall of Fame of cryptographic breakthroughs.

Metrics such as Hex Pattern Similarity or Structural Matching Score are meaningless for hashes of the type SHA-256 → RIPEMD-160, because even the smallest change in the key bits randomly alters all bits of the hash (avalanche effect)
Genetic algorithms are essentially useful in spaces where the fitness score aligns with the goal. However, in the Bitcoin puzzle, taking small steps in the key space does not lead towards the target address
In your log there were some duplicate entries causing wasted I/O and time but even this is insignificant compared to the scale of the problem.
