Agreed.
I find it helpful (to the readers) if we call the second half the trib the "GREAT tribulation" (as it IS in Scripture), rather than labeling the entire 7-yr period "
great tribulation" (as you had, in your post), so that when we talk about the ARRIVAL point in time of "the DOTL," we can be clear that we mean, at the START of the "7-yrs" (rather than at its MID-point, as some believe to be the case when it comes to the "ARRIVAL" of the DOTL time period).
Thank you for clarifying your intention. = )
