As ex-dev(designer to be specific), yeah, and its missing largest misconception ever since steam chart exists.
Daily concurrency =! active players.
Daily concurrency is just that, how many players logged into the game at specific day and how was the peak.
Real metric of player activity is being measured at weekly and monthly retention, because only and exclusively the most hardcore of players play the exact same game on a daily basis.
Daily concurrency dropoff in 2 months post release is normal, anything higher then 90% is "ded gaem", anything between 90 and 70% is regular drop and if daily concurrency retains more then 30% after two months, its jackpot only a handful of games can show.
Bigger indicator then daily peaks is how many players come online during time when new content patches are deployed, because both hardcore and casual, less frequently playing players want to check them out within first couple of days of release and even that is not always true, hence MAU chart, which we have no access to what so ever is the only accurate one for estimating active playerbase.
None of your post means jack shit to someone who is currently in queue looking for a game. This game is dead. No matter how you spin it or try to cope. It is dead. Relic failed. Again. As predicted.
Matching current Coh2 numbers is NOT a success. You are all left to garbage match making again. Coh3 is just a Coh2 turd with some water sprinkled on it to make it seem fresh.
In 6 months or a year, there may be more players. But will it be the number of players there could have been if this release was not a complete joke?
