My 2011 Colorado 4L60E "Desired Shift Time" charts make no sense. The Y-axis is labeled "Transmission Oil Temp" and the values range from 32.75F to 32.52F. All Pattern X, Y and Z, 1-2, 2-3 and 3-4 charts have the same "weird" labeling and values. See the example below.

The Y-axis should have 1 > 2 shift, 2 > 3 shift, etc. What's the deal here??
Perhaps an HPTuners guru could weigh in. PLEASE ASSIST!!
