Unbelievable number of moves in seconds

I have experienced clocks going up when players are running out of time. Apparently this is NOT possible but I did not have time to do screen shots. Today one of my opponents clock was showing seconds and my opponent was still able to make 5 more moves. On review my opponent apparently had 0.4 left and managed to do 5 moves so that is less than 0.1 per move. If this person can move this quick I want to employ for data entry. I have 200GB fibre optic connection so no lagging like some have suggested before. The chess.com experience is getting less and less fun due to very little action being taken by manipulators of the game.
   

Lagging can be caused by the many miles between your fiber and the chess.com servers.

JustBeFair the problem is on Chess.com they are just are not prepared to admit it because many paid customers would leave. If someone is completing such fast moves without their clock representing the time it takes to move it is either a vulnerability in the App or a BUG ( probably both )

Sometimes it's laggy but less frequently ts an automatic bot

But honestly it's mostly server lag

Or just glitchy and neither ? It's not always some conspiracy lag like that happens on plenty of servers

When you move a piece when it's not your turn that piece automatically moves when it's your turn

Your opponent premoved a few moves when low on time. He had a forced mate in two for several moves in a row, but missed it due to moving too fast. Nothing fishy in the speed: at least 0.1 seconds came off every move. Premoving uses 0.1 seconds.

How can you premove 5 times in 0.4 seconds when you do NOT know where your opponent is going to move. On analysis I made 2 engine moves ( more by luck than judgement ) the response should have taken longer than seconds. Or are you saying a player of around 1200 can think this quick, even with premoves as an option without assistance?

It's probably cause t was 4.3 secondes I won a couple games on 0.01 seconds before but the lag can be the server not always your computer so just cause you have good connection doesn't mean you don't have lag and yes there are automatic bots but idk why someone would do that in an endgame with no time on the clock it's a very ineffective and it's a normal to premove in an endgame with no time on the clock it's usually in the opening or middle game it's typically very obvious because it's almost every move

His premoves were safe, but missed a faster checkmate. That's how.
