Most everything in nature follows a Gaussian or normal" distribution. Whether you are measuring height, weight, people's recovery time to the flu, caloric intake, whatever it is; if the sample size is large enough it will exhibit characteristics of a normal or bell shape curve.
The timing or distribution of the rut is no different.
The reaction on forums to early or late breeding would be similar to seeing one of the world's shortest or tallest people. These are more rare, outlying type events that can leave you scratching your head.
Now if u see a breeding pair say on nov 10th, no big deal right. That's like walking past some 5'10" guy at the gas station, ya never look twice. That's because it is expected or "normal".
Very few does are bred in September, just like there are very few 4ft adult-human males.
Very few does are bred in february, just like there are few 7.5+ adult-human males.
Most adult males are 5'9-5'10, much like most of the does are bred in the first 2 weeks of November.
It all boils down to statistics if the sample size is large enough. Don't go crazy reacting to an early or outlier event.
