How the Buzzwhole calculation does in final ranking unbeatable player can go down with one game lost

Hi Team,

Just wanted to understand How the Buzzwhole calculation does in final ranking

unbeatable player can go down with player lost one game and went head with equal point

https://chess-results.com/tnr1073948.aspx?lan=1&art=4&turdet=YES

Vyom Shivmath playing round 7 in top table and draw the final game.. But the 4th row player with 5 point and lost 1 game went head with equal point calculation with buzz hole..

How does this buzz hole calculation work? what all code and criteria they add in clock when its decide the final ranking?  How they update the clock software, How will Players and parents knows, clock does not have any glitch issue which give wrong result.. Can the calculation entry get manipulate?

In Physical game like Cricket, Tennis and Football umpire give the wrong decision.. This can bee seen with the eyes

But in chess how we ensure cheating is not happening with data manipulate or others.

When Arbiter say clock is functioning properly no data manipulation happen? how can we trust on this.. Software can be hacked and manipualate? Anyone monitor from FIDE check clock used by organised does n't have glitch or any data get manipulate or clock glitch they can scan and share second opinion.. Like in Cricket Tennis and Football we have third umpire to recheck and change the decision,,

THanks Prashant
