I don't know if its a glitch?!

So i joined an online road trip, cruising with my P1, waiting for people to finish thier event, so while i was waiting i kept smashing XP boards, and guess what when even finished and 2nd event started, all XP gained from the boards went in the road trip, i missed the first 2 events, but i came in first in the table with over 40,000 points? is that a glitch?
