It's competition results from my climbing centre - usually they're also posted online, but the centre staff aren't given the ability to update the website, and it seems the person who does has forgotten or not bothered.
I could probably ask for an emailed copy, but I don't understand how detecting numerical digits can be difficult.
What's even more frustrating is that it's supposed to be possible to limit Terreract to only detecting digits, but it doesn't work - it turns out they removed the ability to blacklist/whitelist characters in the current version. :@
