Well, assuming that it is correct, the quote you show is not conflicting with the concept of february earnings being paid at the beginning of march.
But this quote doesn’t seem to be representative of the current system anyways (and it is not even gramatically correct …) since it suggests that everyone would get a different payout day (day when 100USD is reached + 30), yet I don’t think that’s the case.
The following quote from the “Learn more about payouts” link is more clear and confirms your interpretation :
So indeed, if payout is normally supposed to happen 30 days after the end of a given month we’ll basically have a one month gap (no payout) this month because of the (exeptionally fast) Jan payout that occurred in early Feb instead of Feb 30th … a few days after the Dec payout (issued on Jan 30th). It makes sense.
There’s definitely some kind of issue going on ATM though (for me at least), as the February report isn’t being generated. Anyways, I suppose we’ll know soon.
