[QUOTE="Warren Jensen, post: 20858, member: 21"] Darryl, It would be interesting to try to quantify the mirage component of the observation, "Sun is up, shots are up". You could do this by keeping detailed records of the air temperature, the ammo temperature, the air pressure, humidity, and shot placement. You could later calculate each component of a rising point of impact and the remainder would be caused by mirage. The components can be calculated very precisely if they are measured precisely. You would have to also place some sort of value on the mirage at the time of each shot. I do not think that this would be valid for anything but the conditions on a certain range. But as we all know, different ranges have conditions that will pattern and thus perhaps the mirage could be patterned, also, for that range. I suspect you guys do this intuitively already, but being an engineer I have a compulsion to try to quantify everything. [/QUOTE]
