How To Play Tin Whistle: A Step-By-Step Guide For Beginners To Master 25 Traditional Irish Tunes, Learn Tin Whistle Techniques, And Play With Confidence

I just started reading this book and unless I am missing something there are several errors in chapter 3 regarding note finger placement. Page 27 says the third hole uncovered to play F# but the diagram shows two open holes, first and fourth (or sixth and third depending on which way he is displaying, which I can't determine). Next on page 32 there are several errors on the closed hole diagrams. I compared to the Clarke fingering chart to make sure since I am new to the tin whistle. Clarke's diagram shows F# as top four covered and bottom two open. I will update if I discover it is my error in understanding.
