I received a note from a Child Development Specialist/Early Interventionist Ms. Carol McCullough who suggested that you should read this chart based on your child's developmental skill and not the chronological age.
This is especially important for parents with developmentally delayed chidren - this chart was developed for children without any developmental delays.
So according to Ms. Carol McCullough the focus should be on the developmental age and not the chronological age. If you child is exhibiting the developmental skills in the last two rows - then your child is probably ready to be potty trained.
