I use the splinterlands api the same way the splinterlands site does. The api is not organized in a concise way for the end user, so that's why i do these kind of reports. For instance, for each group and phase in the tournament i'll make a call like https://api2.splinterlands.com/tournaments/battles?id=4958535b4f5b27e57c062cd79034dd61b3954967&round=1&swiss_group=1 to get all the battles and iterate over them, accumulating whatever i want
