The files are named "challenge_279..." when this is challenge 308...
There is little explanation of the data format so one has to basically GUESS what is the weight/age/height?
Basically have to use RegEx again...
Model output didn't actually "round to 2 decimal places"
Pretty frustrating to work on this one.
We got there in the end :)
I had to wonder if I did the right challenge with the start file name, but this is the right one.
Getting the filters right was key.
It looks like the Output in the start file does not exclude errant data. My counts are off by the number of invalid records.
