Bring your CYA up to the maximum, which for your Jandy unit is 75 ppm (and given the amount of precision in the CYA test I would suggest brining it up to 80 ppm).
Drop your TA to 70-80 ppm (70 ppm is better). (Lower TA means slower pH rise from outgassing of CO2)
Once this is done adjust the FC level in the pool to 4-5 ppm by adjusting cell output and/or pump run time.
Maintain your pH at 7.6 and not lower (the lower you put the pH the faster it rises) and drop it back to 7.6 when it climbs over 7.8.

Finally, consider adding borates to 50 ppm since this will introduce a secondary borate/boric acid pH buffer system that will work in compliment to the bicarbonate/carbonic acid buffer system we call TA and will maintain the pH around 7.6-7.7 for much longer than without the borates.
