Right--I know about the model and what it implies. The question asked was about how to gain an intuitive feel for what's going on, not for an explanation of how the mathematical model works.An other way to visualize the mechanism. In point mass model, wind deflection is proportional to lag time (Tlag), which is the difference between TOF and time (To) the projectile would have taken to travel the same distance in vacuum.
Tlag = TOF - To
In terms of intuitive insight, the TOF-To difference relationship to POI change is actually even more problematic because it sort of implies that the projectile somehow "knows" its flight time in a vacuum.
The point is that it's easy to see that if you have wind acting on a projectile, the longer it acts on the projectile, the more effect that will have on the POI. It's not at all easy to see why, in some cases that you can decrease the time the wind acts on the projectile without decreasing the effect on the POI.
Pointing out that it's a function of the difference between the actual TOF and the theoretical TOF in a vacuum may explain how the model works, but it still doesn't really give someone a good "feel" for why the shorter TOF doesn't result in less POI error.
Also, there's the issue of why this happens sometimes but not other times. Low BC is referenced, (airgun pellets, the referenced projectiles are not just low BC by bullet standards, they are off the charts low) but that implies that there's some sort of BC threshold. What is it? Pellets are usually shot at very low velocities, compared to rifle bullets, is there a limited velocity range where this occurs?
