COMAC C919 Misrepresentation (as usual)

I was accidentally checking performance yesterday, and found some inaccuracies in AS aircraft performance. I was about to post a topic today and then I noticed the discussion here, and some plans (Aircraft Performance System 2.0) to enhance aircraft performance in AS.

It has been a year since this original post but the change has not happened yet. Is it possible to release quick data patches to fix the problem? Do we have to wait for the new system released?

As many of you have noticed, the max payload of A320 and B737 are over-presented, while C919 is under-presented. Making a quick fix will make the game more interesting, like the introduction of SSJ, A220, and 195E2. And introduction of Tu-214 will certainly give us more options given 757 is gone.
