Disagree you may but Topspeed running is my bag . You need to gain 100m to get an extra second on the throttle at the bottom end so it makes no difference as speed gained at 200mph in 1 second is rather limited.
MikeR proved it years ago came hacking around the bottom bend best was a 180.3 run. Lined up from a standing start & set a then record of 180.9mph first time.
I agree it helps the clutch which is why we use the bend but much more efficiently than the Vmax boys do.
