Just google for the report, it shows a 4.5M to 7.8M jump for the quarter. What you write makes sense but there is the obvious gap. It all depends on how consoles have been shipping in the past three months. There could be a full 5 week's supply on ships (by mid-June, around 10.5-10.6M units were produced if manufacturing hasn't increased yet). However, with stocks out worldwide, my guess is some flying-in has occationally been taking place to sooth people in the waiting queue.
We wait for the next fj report to see if that 4.5M to 7.8M was somehow fishy or not. Probably your early numbers were just too high and you have been making "a soft landing" in the past several weeks. Time will tell.
I do want our figures to as accurate as possible. We have to extrapolate figures for many countries with the numbers we do have (US, UK, Spain, Japan), as well as looking at PS4 sales for the same week in its lifetime. Not that it is the best comparison as the PS4 was easier to find than the PS5 is.
