I'm confused about how Sport mode works and displayed print time

In Bambu Studio I sliced the following model and it said the print time would be 2 1/2 hours using what I assume would be standard speed mode. Then after the first layer had completed I went to the BS device page and turned it to sport mode which it seemed to acknowledge by displaying 124%. Then later the print completed and the C1X display said it took the initially estimated 2:30 and the Handy app confirms a start time of 11:08 and an end time of 13:24. So I’m confused about what effect sport mode had on this print at all, I thought I changed it correctly. Any suggestions?
