If you had a pack maintain coil SST and the return air temperature was also maintained, then you slowed the fan speed down, you will see the leaving air temp drop and the TEV superheat drop. But the coil still has the same TD. The return air is constant and the SST is constant but we have slowed the air flow down and must therefore be doing less duty.
I agree you are doing less duty. But you can't slow the fan down, and all perameters stay the same. The TD is not going to stay the same, because the coil temperature is going to drop.
