In the races that have data entered, you were four seconds off the fast lap in one combo. It's not like you're consistently four seconds off the fast lap. Based on the data and the replays I have been able to watch, you spent just as much time racing with someone in D1 as you did in D2. The difference here is that in D2 you were running up front and in D1 your running mid pack to the back for the most part. I will admit, I haven't watch all the replays from the last two months (mostly because D1 is rarely uploaded) but I have watched quite a few. Your fast laps in D1 are faster than anyone in D2 who isn't on the short list to be promoted to D1 and since you are so consistent in those times (your words) you would most likely walk away with D2 just as the guys who are up for promotion (who are running similar laps times to you) did this month.
