The chart looks about right to me.
One thing to help avoid confusion: the description of diametral pitch in your chart is listed as 1/10" pitch. That is actually your circular pitch. The equivalent diametral pitch for that is about 31.416 Dp. Just telling you this in case you get a notion to purchase some kind of tooling and get perplexed when it it 3.14159 times bigger than you expected
First you get good, then you get fast. Then grouchiness sets in.
