Nike+ cut 1min and 30 seconds and 0.2mile - bug report

Bug report
When I have finished a run and stop the nike+ it said 52m25sec... at that I clicked on Home button. When going back to nike+ to sync the time is now 51m05 seconds... and it look s like the distance is cut with 0.2mile as well
This have happened before but does not happen every time..
I have iPhone 4 with iOS 4.1. The iOS v 4.1 have otherwise resolve most of the earlier issues and actually works most and every time.
