I typically do well in events but I can never really be sure how well I did since I cant get the specific rank once the event is over.
It would be great if there was a way to look up past events (even just the last 10 or so)
Then check your rank and alliance rank.
Maybe build it into the web api you have going for the drop percentage data.
Give event stats, user stats, user data, ect all in a nice xml package.. please?
As a workaround, you can take a screenshot as close to end of event and save it for future reference.
Looks like the devs listened to us, recent events history is coming with R51 
well it is a start..
