I'm the author of the plugin; quite honestly surprised to see it mentioned here. It was originally a private and badly written extension which was the result of thoughtlessly trying to increase the functionality of what was initially a simple piece of code. Over time it's been shared with some streamers and a few members of the competitive community, but I had no idea people were actively looking for it here.
The version pictured is very old, but I'm currently in the process of re-writing the plugin to be more manageable and easily extensible, with the intent to add a few new features and possibly release it publicly here given how well-received it has been. I will eventually submit it to the forum and plugin gallery for review, so if and when it's released you can find it there.
If BattleLog should ever make its way to BF1 I will try my best to support it. Sadly it looks like BattleLog is on its way out, but as long as the statistics engine and some sort of HTTP based server-state API exists there should be no problem keeping this running.
Any questions feel free to ask or PM.
