How accurate is public info on SHORTS?

I have no position in GME
I am curious regarding the available information and accuracy of short info for GME.

1- My understanding is GME is reported twice a month to FINRA, and that report is the source for all the short info I can find from various places on the net

2- How are people coming to the conclusion regarding the VALUE of a short, meaning, if the last report was Jan 15, and the next report was due Jan 29, how do we know that the shorts that existed Jan 1 to 15'th are the same shorts and BASIS as whatever is reported on the 29'th. How do we know that shorts created from 15 to 29 arent on a new metorriffic scale that is the same as the new stock price, making them meaningless for a squeeze Monday forward if they are now based on 500 400 300 dollars ?

3- I found one report that makes no sense to me,

https://www.marketbeat.com/stocks/NYSE/gme/short-interest/

I noticed in the field PERCENTAGE FLOAT it drops to 0% going forward, and this totally coincides with the release date of ROARING KITTY aka DEEPFUCKINGVALUEs first GME youtube video in July 2020 with his DD and a lot of emphasis on the extreme short interest at that time. I dont understand why PERCENTAGE FLOAT drops and stays at 0% even today.
