Ok got it. In order to keep the CSI positive for the time being is it wise/safe to push any of the parameters used to calculate outside of their recommended range? Currently it seems as if I can raise my TA to about 90 to help get up closer to a CSI at zero. But with CH where its at I'm not seeing how to get up to that range while staying within the target levels. And as always thank you so much for the help. I know I have a lot of questions and your teaching is greatly appreciated.
