Thanks Gary, thats great help thanks.
could you confirm what happens if you have a high load and a low load??
I'm assuming with a high load the SCT will reduce below 11-19K above air on to condenser and with a low load the SCT will increase to more than 11-19k above air on to cond.

Just the opposite. High load increases SCT and low load decreases SCT... and SCT above ambient (cond TD) should remain within the 11-19K range.
