Unofficial UK Slalom BBS

I am planning on making a free slalom specific program to help monitor slalom training performance. It will be a database system with logins and registration. The plan is to have functionality to take times recorded from a repeatable tests and provide personal bests, percentage peak performances and other statistical information from training. Does anyone have any suggestions that they think a training performance tracker should include? I mean, would people want an option to store race points and rebuild an integrated ranking with comparisons? any thoughts or ideas for it are appreciated.

Thanks
Jamie

As a non paddler, I've no idea what the data should include, but for something like this, it would be nice to see some graphical representations of the data.
