If the ambient air onto the condenser remains the same and the sct increases with high load then the cond td must get smaller.

do you mean that with a high load the cond td would be around 11k (smaller) and low load would be around 19k (larger)

No... No... and No.

Let's say the ambient is 25C and the SCT is 36C. The TD is 36-25=11K.

The SCT then rises to 40C. The TD is 40-25=15K .
