SMH. LOL.
You didn't have time to watch the video yet. Debunk it please.
It would be a positive number expression of time. On your spreadsheet chartoon, notice that you calculate T = Tb - Ts. You calculate elapsed time as the time it took the bullet to travel, minus the time it took the sound to travel. The correct formula should be T = Ts – Tb = d/Vs – d/Vb. As the bullet is supersonic, and sound is a constant, the sound would travel 400 yards in 1.06s and the bullet would travel in less than 1.06s. Subtracting 1.06 from a smaller number will always yield a negative number. At 1200 feet, you calculate Tb as 0.448578s, and Ts as 1.062s and calculate the T as -0.6126, negative 0.6126 seconds. The average donkey could recognize that something is wrong when the result is negative time. Just what do you think happens in negative 0.6126 seconds? You could at least recognize that if you get a negative number, you have stated the required formula backwards, and you proceeded to perform the calculation backwards, and present the bass ackwards result of your misunderstanding of the study you looked at. Moreover, while you state backwards that T = Tb - Ts, your spreadsheet never defines what T is supposed to represent. Negative 0.6126 is the time of what? What is the significance of this negative 0.6126 seconds (other than to demonstrate you did not understand the reference study)?
>>The correct formula should be T = Ts – Tb = d/Vs – d/Vb. Nope. You're not even reading from the relevant part of the paper - where the microphone adjacent to the victim scenario is discussed. http://ww w.btgresearch.org/AcousticReconstruction02042012.pdf That's the same formula I have in my illustration:
No, I read the correct part. The formula is correct for a supersonic bullet only if the value is explicitly expressed as an absolute. Otherwise, the correct value is derived by changing the formula. Either will work. You did neither and derived negative times and published them that way.

>>No, I read the correct part. LOL Here's what you quoted: ==================== A microphone was placed a few centimeters from the muzzle to record both the muzzle blast and the sound of the bullet hitting the deer. The time recorded between the muzzle blast and bullet striking the target represents the sum of the bullet time of flight (tb) and the time for the sound to return to the microphone from the target (ts), nolu chan posted on 2017-10-25 16:15:25 ET https://libertysflame.com/cgi- bin/readart.cgi?ArtNum=53025&Disp=120#C120 ==================== And this is the correct section of the paper that deals with a microphone AT THE TARGET, the scenario where the "shooter dressed as police" video in question was taken. http://ww w.btgresearch.org/AcousticReconstruction02042012.pdf >>The formula is correct for a supersonic bullet only if the value is explicitly expressed as an absolute The formula is fine just the way the authors of the paper wrote it. The negative time is perfectly acceptable IF you actually understand what the value and chart are saying: The sound of the Report (Ts) event was recorded 0.6126 seconds after Tb and that time differential corresponds to a distance of 1200 ft from the shooter.

Debunk it please.
What would the Elapsed time between the Last Report sound event and the Last Bullet sound event be if, as the video alleged, the guy "dressed as police" was shooting?

t = ts + tb = d/Vs + d/Vb
