If you take your ETC TQ request and divided it by the engine brake torque you get the torque ratio. Notice that if the request is higher than the engine torque the ratio will be larger than 1 and if its less it will be less than 1. The Fuel cut torque ratio is only used when ETC is less than engine torque(ratio less than 1) as you don't want it to cut fuel and cause a lean condition when the engine is being requested to make more power. That's why it can only cut fuel below a 1 ratio. Coyote cook book says to raise this to 1 but does not explain why. Above 1 it uses spark and ETC to limit torque. Also notice the spark only torque ratio is used when ever the ratio is above 0. So it can cut spark any time the engine is not in DFCO basically. Anywhere between 0 and 1 it can use one of the three it sees fit or a combination.
I looked through your log and see at WOT your torque ratio is .85 to .99. If you don't want to risk a fuel cut at WOT I would suggest lowering your fuel cut torque ratio for DD to less than this not to low or you will get spark and ETC rather than fuel cuts. If you want it to stop pulling spark you need to raise the spark only torque ratio above .99. Or you can manipulate the DD torque/TB model to change the values of this ratio at WOT. hopefully this clears up where you are trying to get to with the torque values.
