TOPIC: Benchmarking Deja Vu

Benchmarking Deja Vu 1 year, 2 months ago #16509

Tom, Paul, and I went over towards Gibsland yesterday to scratch a benchmarking itch. We found a few, but mostly found some NGS description problems with their datasheets on a level line. Which you can see below:

I decided that I had to go scratch my benchmarking itch today, and took a few friends on some that appeared to have no recoveries since monumentation in 1977. Once we arrived on a certain level line, the descriptions gave me deja vu.

I know it's just database entry errors, but I have never encountered this, and with ones so close in a line. You can see the numerical pattern, that every fourth one is the same. None of these marks were successfully recovered. It definitely had us scratching our heads after the second one the same, but we finally gave up after so many. LOL
