The wave 2 (ABC correction) would be completed at 1932.
So "if" (ever big IF) the count is correct we are in the 1st wave of the big 3. This 3-1 would be complete at around 1865, then we could see the ABC up for the 2nd inside this 3. In this case we should have 2 short entries (and in case 1 long for the ABC up):
---------------------------
1st short:
Entry area: 1900 - 1906
TG: 1866
---------------------------
2nd short:
1907 - 1912
TG: 1740
---------------------------
Optional long (for the ABC):
Entry area: 1866 - 1864
TG: 1905
---------------------------
This is an update of my previous ideas (linked below).
