I'm with the camp that prefers to get their SWUs Jan-Jan. Crediting in Nov/Dec (when I usually requalify) is less beneficial to me. I would also be in favour of spreading out our SWU crediting similar to the current CR1 system. 1 or 2 SWUs per 25,000 BIS UA miles means no major push to use all SWUs at the end of next year and also be a soft landing for those that won't / can't re-qualify as 1K the following year.
