First off ignore anything strava says for short distances in general, but especially on a track. The gps satilites are just not very accurate.
Before training on the track you need to get a real feel what its like to move around on the track. And that is not really possible by yourself. There are lots of things that happen that you will never realize until you have been racing for a while. So if you have a friend that races get them to do some follow the leader stuff, or go out on a training day.
