Reading through Jandy's AquaPure manual, they only recommend 1-3ppm free chlorine at ~80CYA, while Pool Math recommends 6ppm.
Why the difference?

The pool industry has been cut and pasting the same government recommendations for pool water chemistry for over 30 years without any updates in the science.
ALL the pool industry is still ignoring the relationship of FC and CYA ... the 1-3 ppm number is meaningless once there is CYA in the water. You don’t find the FC/CYA Levels in equipment manuals.
Your pool will be less harsh following the TFP recommendations than a public un-stabilized pool. In fact, even at the shock level FC for your CYA, that is STILL a lower active chlorine level than a pool with 0 CYA and 2ppm FC.
I suggest you read ABCs of Pool Water Chemistry.
