That growth chart does give you an idea how big fry should be. However, don't be discouraged if your fry is growing slower. Fry growth depends on a number of factors; food, water, genetics, and mentality. Often, we can't duplicate the exact conditions to power grow fry evenly.
In fact, sometimes I am confused by growth rate of fry accidentally siphoned into "waste" buckets. Poor water, smaller container, and not fed, but can grow faster than those I pamper.
