Driving me mad. All I can think of in reference to OWI_Pete's hint about looking for patterns and things that don't match up is that the second string of numbers only has 6 slashes, whereas the rest have 8. I can't figure out what that means or what to do with it though.
I tried looking at it really literally for a while; as in the /'s signify things we need, and discard the rest. So I put the number of forward slashes at the end of each line in green; I then looked at the second line, which only has "1 forward slash", so I assumed there was "1 true" value in that row. I then found only 1 value that was present in both the first and second line, being "5,5.2", so I assumed that must be the correct one for that line, so I marked it as green, and then marked the rest of the row as red.
But then there's the flaws in that method: Why would there only be 5 backward slashes in line 2 if there was 11 "unneeded" values? Also, "7,5.3" appears in both the 2nd and 3rd line, so that could be the "true" value. Really tried taking it back to basics there, but there's a few holes in the logic.
I don't actually think this is the correct method, just posting this in case it gives anyone a brainwave haha.
