Dragtimes also has the Rock listed at 211ft of elevation which is incorrect from what I am seeing on other sites. An extra +250 over what was quoted doesn't make back much time of mph but I like to be accurate when comparing things.
I have found Dragtimes to be pretty inaccurate. A better site to use is: airdensityonline.com

It will give you DA along with real time weather conditions. Water grains is a big item many overlook.
