Hi there,

This edit is not correct, the Sports Centre tag is for the entire building, not individual objects. I don't think there's a standardized way in OpenStreetMap to tag diving boards, so you may have to do some research on the wiki: https://wiki.openstreetmap.org/wiki/Main_Page

I'm going to remove some of the tags so that people don't get confused, feel free to edit it once you figured out what to do.
