SWG and CYA

I have a Pentair iChlor30 SWG. Reading the manual suggests the CYA levels to be in the 30-50 range. Reading posts in this forum, it seems like the recommendation is to keep pools with SWG in the levels at 50-70 for CYA. Should I follow the Pentair manual in the 30-50 range or bring the CYA levels up to 50-70? Keeping my chlorine levels (FC & TC) has been a bit of a challenge so far this season. This is my first year with the pool.
