Daily SRL Activity Stats

I would like to pull activity stats for SRL racing on a daily basis with the amount detail one would get with a call to http://www.bungie.net/Platform/Destiny/Stats/ActivityHistory/{membershipType}/{destinyMembershipId}/{characterId}/ I had thought it was possible using the call http://www.bungie.net/Platform/Destiny/Stats/{membershipType}/{destinyMembershipId}/{characterId}/?periodType=1&modes=Racing&groups=General&dayStart=2015-12-21&dayend=2015-12-21 Unfortunately, the amount of detail is much less. Am I doing something wrong? Is there a better approach? Thanks, Jason
