@desolutionist I believe mtggoldfish had a bot to scrape data from all the events, so it's definitely possible. It's not like MTGO has an API to pull this data from though so I never seriously considered attempting to automate this. It would certainly be great if someone wants to look into this route.
As a less daunting task, someone could figure out how to take a screengrab of the results from every round and convert it into text that's easier to work with. Several of us tried to figure out a way to do this over a year ago, but after minimal effort led to incomplete results we gave up. It's much easier to do metagame analyses for paper events because I just open the .WER file in notepad and parse the results.
