Yes. When the airport was first built, they graded from the middle to the ends. They decided not to grade it perfectly flat, or perfectly level. It slopes 2.x deg up to the SW and it has a very noticeable crown. On takeoff either direction but more to the SW, the runway 'appears' to grow longer with forward motion.The hump in the middle is such a strange thing for a runway. Is that a grandfathered standard?
For me, it makes me itchy to rotate early. I've heard this from other pilots taking off as well. There's no reason not to just accelerate to proper Vr speed, but it's common to pull it off too early and get into the reverse command(back side of power curve) region, where further rotation causes more drag, and no acceleration. For those that fly into AVX, on takeoff make sure to monitor your ASI and don't worry, there's more runway ahead of you than appears while rolling. This is even more pronounced after dark.
