You seem to know a lot about the Gaussian curve. Then you know that the real question is how big the standard deviation is.
Imo not so big. Haven't seen a lot of "natural freaks" and variation. That isn't to say it doesn't exist, but it is highly uncommon and the differences must be small.
Honestly, I don't know that much, but this is elementary stuff. I don't like term "small". What is small? In order to tell something about SD you would need to take at least 100 naturals that satisfy no one's condition. I don't have enough experience to cast any predictions. In fact, vast majority of people I know that are worth shit when it comes to physique are far from natural.
break this down for me please im curious.
It is really simple. When you take basically any variable the amount of people that are worse than average by some value is more or less equal than the amount of people that are better by the same value than average. This is so called normal distribution. For example, the amount of people that are 165cm tall is equal to the number of people that are 205cm tall, if the average if 185cm.
Normal distribution depends on two variables: average and standard deviation (SD). Average is pretty obvious. Lower standard deviation tells you that many objects (in this case: bodybuilders) are close to the average.
If you just calculate lean bodymass of population then it is obvious that SD will be high. Constraints you have made on popopulation:
- only those who train seriously
- >5 years lifting
- white
- male
- same height
Will most likely lower the SD, as you intuitevely know, BUT, there will be still guys that are outside of that.
In short, for every shitzo there must be a groink. That's the beauty of math, it fucking works.
