The Minigame DLCs have a focus on speed given that a final time is given after completion and I found it quite enjoyable to better each short run even by just seconds. I was slightly confused to see that a category for 'A shocking turn of events' and 'The I in Team' didn't exist.

The Bioshock DLC challenge room times can be found on the Bioshock game page under Individual Level runs

My mistake, I should have looked more thoroughly. Thanks for the info.
