Hi Parutakupiu, there's no "disturbance"!  Sorry for not replying on the WikiProject page - sometimes I have an immediate opinion on a topic and I will reply quickly, and sometimes I need to think about something, so I take some time.

In this case, I guess I'm not sure about your proposal.  The templates certainly look good, so there's no issue there, but I'm weighing the pros and cons of another set of navigation boxes.  I think there are instances on Wikipedia where proper use of categories and list pages are probably sufficient to navigate a topic, and other places where navigation boxes really are desired.  For example, many athlete pages have an excessive use of navigation boxes, in my opinion.  Take a look at Toni Sailer, for example.  At least those five navigation boxes now utilize the show/hide feature - that page was very cluttered before.  Even so, I'm not sure that it is a natural way for readers to want to navigate through Wikipedia.  Do we really need a navigation box to go from one winner in a specific event at the world championships to the next?  Wouldn't it be just as easy to have a "See also" section with links to List of Olympic medalists in alpine skiing and List of Alpine Skiing World Champions and navigate from there?

It's not exactly a parallel situation, but perhaps the concept is similar  the question to be answered is do we really need this new set of navigation boxes (which will number around 350-400 if we make them for all events) or are a set of categories and the existing medalist lists sufficient?  I currently don't have a solid opinion on this myself, so I haven't offered one in response to your request on the WikiProject page.  However, if you have a logical position to support whichever path you take, and can lay the foundation for a consistent implementation across all events (not just diving), then I would support you either way.  Consistency is my biggest concern here.  Hope this helps,
