Also wouldn't it make more sense to update the game to have premoves to be timed on each device rather than transmitting the signal to the server? Premoves should be equal for everyone. I say it must be 0.1sec for all, not favor the one with good wifi.
That's not how it was decided. Players with higher lag or connection problems could result in games that last a lot longer that anticipated based on the time controls if it worked that way.
So, premoves take a minimum of 0.1 second, but if a member is experiencing more lag (or disconnects) over a series of moves than the configured allowance, more time will come off the clock
Wait, you mean clocks were always on server and whenever opponent switched apps, people had to wait for them to come back for 20 seconds every move? Chess.com was letting people do that? This doesn't make sense either. Just how long have you been working for chess.com? Maybe there's something you missed out?
No. The server clocks are always running when a player is on the move, regardless of if they're in the interface or not, or are disconnected. The server updates the client clocks, after moves have been received, to account for lag compensation.
