There isn't a direct correlation between lines of code, and time it takes to update. If you go to the honorbuddy discord server, you will see their explanation in full detail in the announcements page.
Basically, reverse engineering a game-client doesn't fit into a standard application development cycle. They will only let us know updates when "milestones" are met.
We will only get an ETA when it is about 8 hours from release, per discord announcements.
I'd love a lot more insight into what Raphus and EchoTiger do, but it's a waste of their time to keep writing updates saying the same thing "its not ready". Also, they probably don't want to reveal all their "tricks".
All this culminates into us having to patiently wait for the next release.
