Extra Scouting XP...?

I just completed my first 2 races, and according to the guide you're supposed to get 40XP for scouting and development per race. For some reason, in the last race, I earned 52 scouting XP rather than just 40 and now it's messed up the equality between the development and scouting XP.

At the moment, I have 102 scouting XP and 90 development XP. Shouldn't they be equal?

You get extra points for achievents. https://igpmanager.com/play/?url=manager-profile/31729
I have for scouting 22 more XP than for dev.

Scouting XP and Development XP do not stay matched for long, my Scouting XP is 4577 and Development XP is 4575.
