The missing page has arrived. It is the muddiest image of all, so bear with this. On 4 May, Worsley performs an observation and reduction. He determines his latitude to be 55 deg 31'S and his longitude to be 44 deg 13'W On 5 May, Worsley estimates his position to be 54 deg 30'S and 42 deg 36' W, by dead reckoning. They see a bird. On 6 May, Worsley estimates his position to be 54 deg 26' S and 40 deg 44' W, again by dead reckoning. I would like to revise my speculation at this point. South Georgia Island has a northern most point at Bird Island, around 54 deg 0'S. The southernmost point of SGI is around 54 deg 50'S. It appears as if George was right, they tried to sail directly to SGI from Elephant Island. When they reached the appropriate mid-point of the latitude of SGI (54 deg 30'S), they found no island! Gasp! Was it east or west? With Bird Island just over 38 degrees W, I speculate that they chose to steer east.
