If anything, these refinement events normally come during the 1st week of the month, not always though. This refinement event are also normally 4 weeks apart on average based on the past (almost a) year.
And they have said the recent refinement event is NOT a replacement for the wishing credit ones, they are 2 events that will work hand in hand. So just at least like what the above guy posted, wait till July 6th at least.
