there used to be some way to hijack the graphing capabilities by supplying your own csv export of the sport-ident data. I think the western canadians used this for results once. the problem is that it only worked for the single-day event format, and now it's an outdated version of the graph applet.
this avoids some of the problems vlad described since it doesn't actually import anything, it just loads the data from a linked file. but then you can't really do anything interesting like add comments. perhaps a model where users can manually "claim" their SI splits would allow them to be imported cleanly into the attackpoint db for commenting, etc. and unclaimed splits could still show up in the graph. but then I never got around to doing that two years ago either. don't hold your breath...
here's an example of how it used to work:
