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
