I'm no math genius. But 1691 renders > 1671 renders.
And here you are, still waiting for each update despite this deplorable record. You could be doing anything else. Writing about any other visual novel that you don't seem to have a problem with. But here you are. I wonder how many accounts you've created and had closed? Or is this account you use just to troll WVM?
I'm no math genius either but 52/52 has not been achieved and it won't happen at this point. Pretty sure we all know basic math same as you. He clearly missed that mark and continues to miss that mark. 20 renders over, while it technically surpasses his goal, was simply a happy accident because he couldn't leave an ending hanging in mid-conversation. So, yes, technically he produced more renders than he projected. For once he was ahead, but still behind on release dates.
He should come clean and admit (he won't) his proposed schedule is not feasible and that he needs to set a more realistic expectation, both for himself and those who play this AVN. Perhaps not having a schedule at all? Announcing a release date once he has a completed product ready to release like most any reputable developer would do. That relieves the pressure on him and the expectations of the players.
I wish McKenzie had been a real human being. A production manager, because that's what he needs. He needs someone to hold him to his schedule and realistic expectations on what he can and cannot provide based on that schedule. That's really the crux of the situation here. It always has been. He's never been able to adhere to his own proposed schedule. All that anyone complaining wants is for him to do what he says he's going to do (and maybe less duck faces). No one is making that schedule up but him.
All of the above reasons are why people complain. You know why they complain? Because they like the game. They are entrusting that the person creating it, who is giving them their word that releases will happen on a schedule, set by him, happen on that schedule. When they don't happen, it is a disappointment. It's a disappointment because it was something they were looking forward to that was delayed. If it happens occasionally, that's understandable. Real life happens (some people can't accept this). When it becomes a predictable pattern, so much so that it becomes a running joke, he has no one else to blame but himself. The comments then ensue and as unfortunate as it is, they are well earned.
