German Regular Verb Conjugation in the Present Tense

This my first flowchart on the blog, breaking down regular verb conjugation in the present tense in German. I don't think it makes things as easy as I had hoped. Maybe a table would be better? I guess I should include tables on the blog too - maybe any visual way to organize and explain something?

NOTE: 'e' only to be added before 'st' or 't' when the last letter of the root is a 'd' or 't'
