as per other threads am struggling with CYA dwindles
have K2005 and TF100
CYA with TF100 is between 30 and 40
CYA with K2005 is 50
each done over several times
also
on this site I see CYA error may be ±15 and ±10
super guy at Bellevue PoolPro (no retail just service) says CYA is ±10%
tech support at Taylor email said they give no ± for CYA as individual eyes are so different, just believe the result (sort of a theological test I guess)
so then
do I go with the K2005 value or the TF100 value
