Sure, but the Jhana factors described are as in the Suttas, and the mode of concentration reads a lot like MN 111: http://www.accesstoinsight.org/tipitaka ... .than.html
"There was the case where Sariputta — quite secluded from sensuality, secluded from unskillful qualities — entered & remained in the first jhana: rapture & pleasure born of seclusion, accompanied by directed thought & evaluation. Whatever qualities there are in the first jhana — directed thought, evaluation, rapture, pleasure, singleness of mind, contact, feeling, perception, intention, consciousness, desire, decision, persistence, mindfulness, equanimity, & attention — he ferreted them out one after another. Known to him they arose, known to him they remained, known to him they subsided. He discerned, 'So this is how these qualities, not having been, come into play. Having been, they vanish.' He remained unattracted & unrepelled with regard to those qualities, independent, detached, released, dissociated, with an awareness rid of barriers. He discerned that 'There is a further escape,' and pursuing it there really was for him.
[Off-topic in this section, but the progression described by U Pandita is essentially the Classical Progress of Insight described in the Visuddhimagga. Which one assumes was also based on the experience of practitioners, and which Mahasi Sayadaw has written about explicitly http://aimwell.org/Books/Mahasi/Progress/progress.html
. However, the progress of Insight is a considerable elaboration on the sutta discussions of insight. See, for example: http://dhammawheel.com/viewtopic.php?f=25&t=11701&p=177835#p177835
