No.
As I've already said: the 'type' of player on console using any type of journal upload client is more likely to be the dedicated player as opposed to the casual.
I think that gives a fair indication of volume though: casual players are much more likely to dip in and out infrequently, whereas dedicated console players are more likely to run an upload client of some form consistently.
Therefore any decline in that volume is indicative of a trend amongst dedicated Elite players on console.
Isn't that a presumption though, or do you have evidence of it being fact?
Serious question.
