Is this possibly just a typo or the Arista Premium 400 is not exactly Tri-X?
Another possibility is that Kodak (if they supplied times to Freestyle) and Ilford disagree on the time required for this combination. Such differences do happen. Do you happen to have Kodak's suggested time for Tir-X in DDX 1+4 available? If it matches Freestyle's time for Premium 400, then that's the answer.
