Can players make multiple turns in a millisecond?

Hi, all.

Thought I could win last 3 minute blitz game on time (which I became very mindful of in last ~10 seconds: https://www.chess.com/live/game/3338946641). During that interval I watched as my opponents clock seemed to almost be replenishing in our last 20 turns.

At move 52, w 10 seconds on clock for my opponent, he made 3 moves within a millisecond, then at move 55 made another 3 moves within 4 milliseconds.  I don’t run out the clock as a matter of custom and practice, but the rapidity of his move turnaround seems to me impossible. 

Can someone make that many moves in milliseconds or are chess.com clocks occasionally “off”?  Any ideas?

Thanks in advance for your attention and any assistance.

Yes

It's called making pre-moves on Chess.com.

Premoves take 0.1 seconds per move. They're never instant.

So hypothetically, if you had a forced mate in 4, but you only had 0.3 seconds left on the clock, then you're doomed to lose the game, even though you've premoved the mating net.

Realistically you could never win - he had 22 seconds left when he eliminated your last pawn at which point you could no longer have won. It actually took him far far longer to mate than it should have done. 

A millisecond is 0.001 seconds.

In practical terms, the fastest humans can react to a stimulus is a few hundred milliseconds.

Anyway, most places online let you premove.

Premoves cost 1 decisecond, which is 0.1 seconds.

On some sites premoves cost no time, which is how people (like me) can make 20 moves in less than 5 seconds: https://www.chess.com/forum/view/general/5-seconds-vs-1-minute

(and how GMs can play even faster)

Also, it's possible to move in the 0.2 to 0.5 second range even without premoves by picking up a piece and hovering it over the intended square during your opponent's turn. Mentally you set up triggers for which moves you will/won't release the mouse button.

On sites where you can't hover (as there were many years ago) you could constantly click to move a piece so that you essentially instantly move after your opponent's turn. Again this would be in the 0.2 to 0.5 second rage no premoves necessary.

Thanks to most of you for your constructive input. Perhaps the most useful was the help in realizing I’ve been using the word “millisecond” wrong the whole of my 45 year life!  Decasecond. Of course.

Damn you Imperial System of Measurement!

A decasecond would be ten seconds, a decisecond is 1/10 of a second.  https://en.wikipedia.org/wiki/Deca-

Ugh!  Lol, right, “decisecond”!  Thanks.

Ugh...

Nah, it is just premoving, it is a feature you can turn on or turn off in settings.

Honestly, your first few moves should be memorized. 

Or you could go on settings, click "enable premoves" and use them yourself. It's neither cheating nor a malfunction.

No, a millisecond is faster than a frame
