Took me 3 days to realize, but Astuces II p50, the Nuages intro has 2 errors, I believe.
First line, 12th note should have 5-7-5 hammmer on/off, so making the phrase the familiar 7-5-7-5-4-5 on the G string. Likewise 3rd line 9th note should be a 5 instead of 4 (d) also making the sequence 7-5-7-5-4-5 on the A string.
