Not sure, it could be over 50% of the 5k had to have been spent after 4/15 or something since OP didn’t get the 3 nights. I would guess that if you were at $4,500 on 4/15 and spent the extra $500 you might not get it.

Maybe it’s 2 separate counters running concurrently as well.

Meaning -

If you were at $2,500 spend on 4/15 then on 4/18 spent $2,500 you’d hit the 5k mark for the 2 nights. Then spending another $2,500 you’d hit the 3rd night mark and have the 3rd night added, while being only another $2,500 away from 2 more nights.

Its definitely a possibility and as more datapoints come in we’ll be able to track more of how it’s working.
