8/3 2:02

The labelling on the 1:39 chart shows that we should be in the 2nd abc of a double zigzag.  Whether the low at 12:28 is wave i or wave a does not matter.  If it is wave a then a simple 5-wave down from the high at 12:57 should finish off the Z wave, the 2nd zigzap and obstensibly the correction.
