The 5-lap is actually Non NBT as usual.
I only added a startboost for the flap, which is 17"24 now. My Non NBT flap of 17"27 is relatively better though, because I would say a startboost wins slightly more than 0"03 eventhough you can't take full advantage of it on RR (due to location of corner 1).
Anyway the quality of my RR video's deeply suck (due to some webcam-related issue that I don't totally understand, it might also have to do with neon colors in combination of black background of the track...anyway the video's look psychedelic

), so I chose not to film a 5-lap race. I do have the Non NBT flap on tape, and here is a teaser of the quality of my RR vids

This is a video of a 17"57 opener (best is 55):
