Based on Krishnamacharya's early Mysore texts, Yoga Makaranda (1934) Yogasanagalu (1941) and his later teaching as presented by Srivatsa Ramaswami's as Vinyasa Krama.
Formally titled: Krishnamacharya's Slow Ashtanga Vinyasa Krama Yoga...at Home and Ashtanga Jump back... at Home
The Introduction (translation may be on it's way).
Notice that this is the fourth (expanded) edition and that it's written in the Kanada language which suggests Mysore. We also see above that it was published by Mysore university.
When was Yogasanagalu first published?
I'd always assumed that this was a later text and that there had been a shift in Krishnamacharya's teaching style from something more in keeping with Pattabhi Jois' Ashtanga to Ramaswami's Vinyasa Krama or Desikachar's Viniyoga. These scans of the Yogasanagalu had been sent to me while I was on Ramaswami's TT course and seemed to be exactly what I was learning from Ramaswami. How to square that with the Ashtanga style I had originally practiced, surely there had been a change of approach from when Krishnamcharya left the large group of kids at the Mysore palace to teach one-to-one in Chennai.
It appears that Yogasanagalu was actually first published in 1941, slap bang in the middle of Krishnamacharya's Mysore period, six years after his Yoga Makaranda and at the same time as he was teaching Indra Devi, Iyengar and Pattabhi Jois.
There was no early/ late Krishnamacharya, and his teaching now appears quite consistent throughout his life, no Kehre (turn), no softening of the practice with age.
Ashtanga doesn't represent Krishnamacharya's early style of teaching, it seems more a representation of how Krishnamacharya taught in a particular environment and in a particular set of circumstances i.e. the kids of the Mysore palace (and perhaps Pattabhi Jois' development or codification of that period as it seems he was asked to teach some of Krishnamacharya's classes). This would explain the 1938 movie, we see Iyengar doing an Ashtanga style demonstration (very out of keeping with the Iyengar yoga we're familiar with that he was developing in the 40's and 50's) and yet Krishnamacharya practicing in a more 'Vinyasa Krama' style.
*If anyone has a translation of the yogasanagalu or at least a summery I would love to see it, my email can be found in the ABOUT ME section of this blog.

from Kalama sutra, translation from the Pali by Bhikkhu Bodhi This blog included. "So, as I said, Kalamas: 'Don't go by reports, by legends, by traditions, by scripture, by logical conjecture, by inference, by analogies, by agreement through pondering views, by probability, or by the thought, "This contemplative is our teacher." When you know for yourselves that, "These qualities are unskillful; these qualities are blameworthy; these qualities are criticized by the wise; these qualities, when adopted & carried out, lead to harm & to suffering" — then you should abandon them.' Thus was it said. And in reference to this was it said.
"Now, Kalamas, don't go by reports, by legends, by traditions, by scripture, by logical conjecture, by inference, by analogies, by agreement through pondering views, by probability, or by the thought, 'This contemplative is our teacher.' When you know for yourselves that, 'These qualities are skillful; these qualities are blameless; these qualities are praised by the wise; these qualities, when adopted & carried out, lead to welfare & to happiness' — then you should enter & remain in them.
