[quote=Anonymous]The curves were drawn so we can easily see the data. It’s not predictive. No pediatrician looks at a newborn born in the 99th percentile for weight and predicts that she will be 175 lbs at age 17. The curve isn’t a pathway. It’s an artificial line that has been fitted to individual data points at each time point. If the cdc had taken all baby girls born at the 5th percentile for weight, graphed their weight and height over time until they reached age 20, and then used either algebraic or geometric means to fit a curve to the data, then that curve could be useful for determining your best guess for growth, as long as the data wasn’t too “noisy”. But that’s not how it’s done. There is no “falling off the curve” because the curve doesn’t represent anyone’s growth pattern or anyone’s goal growth pattern. You should treat the numbers like you treat bmi. It’s a data point. It doesn’t tell you what the next data point will be. [/quote]
