On Tuesday, all the business class fares are C bucket and pricing at $2439.
Wednesday, all the business class fares are J bucket and clocking in at $4499 with some flights completely sold out.
Thursday, except for the last two redeyes that are J/$4499, all flights completely sold out in business.
Friday and Saturday back to all business class fares are C bucket and $2439.

And I realize seatmaps are not an indicator of loads, but for the days that only C and J fares are available, there seem to be quite a few seats showing as open.
