My SWU deposits were based on BIS miles.
I reached 125K EQMs in early June and reached 125K BIS miles on 7/25. 2 SWUs showed up in my account on 8/1.
I reached 150 EQMs in early September. I crossed the 150K BIS level on 10/31. The 2 SWUs showed up in my account on 11/8.
That's in addition to the four early 2005 SWUs which showed up on 10/14.
