So, when you're throttling-up from 250 Knots you begin the process of turning the lamps off? This doesn't sound right. The 18,000 foot mark does though...That's about where they are at this point and they're up around 400 Knots. Nearly all of the aircraft are within a few minutes of eachother doing this on this route.
Ahh...I hear one passing over me now. Must be a DC-9-XX if I can hear him!
