Note the flip flop shown between the center DS chart and the yellow wt mag 1984. Note: In the Chart the anointed generation will not enter the Great Tribulation, are absent at Armageddon, but the yellow wt mag reads : " some of them will not pass away until all things occur. Not just the timing is wrong, the identity too.
Note that the life line for the generation stops prior to The Great Tribulation/ Armageddon field with David, in accord with their rapture teaching.
