No.
Some animals plateau - you feed them and feed them and they maintain and then one day the weight starts climbing - whether it be at 6 months or 8 months or whatever.
Others don't. They gain and they gain and they gain until they are older and then they tend to level off.
Others grow in different ways. Nothing is black and white and there is no definitive consensus on what a healthy six month old snake should reasonably weigh.
You didn't hit a nerve, you made a statement imparted a black on white view on a situation that has many variables. While making that statement, you took a swipe (inadvertent?) at some people who have a pretty good idea how to raise a healthy snake.
