It's one of those things, where on the weeks with sub 1 minute laps times, a few tenths makes a HUGE difference in Handicap. If you were just 3 tenths faster, you likely would have been placed in D2 gold.
That's part of the point of spreading it across 3 events, so that you are placed on a variety of events without us being chained to qualifiers for which time cutoffs have to be adjusted with game updates.
Some drivers might choose to procure their events to those which suit them, but if you just run consecutively like you did, I would simply view it as an accurate representation of your ability in those three events.
Unless, of course, you are saying you did not try hard enough in week 8. That would be sandbagging.
