Interesting.Yes, I had my ECA done by WES, duplicate ordered on November 2 and sent on November 3 according to the WES website.
What's your theory?
It had passed my mind that WES double checking could be faster than IQAS double checking, since one depends on the candidate while the other is out of the candidate's reach (you don't order an IQAS duplicate, OINP verifies those by themselves).
But seeing cases go to Assessment in 11 to 24 days (your case, the slowest so far) just makes me conclude the obvious - IT'S ALL RANDOM :/
