Your image is king of vague. We have to trust the math you say you did. This is much more thorough and understandable.

Don't you find it a little odd that he doesn't present any actual data or audio? The model audio he's describing (without presenting any actual data) fits the scenario where the microphone is adjacent to the target: [Using Sound of Target Impact for Acoustic Reconstructions of Shooting Events] http:// www.btgresearch.org/AcousticReconstruction02042012.pdf "For example, if the microphone is adjacent to the victim (such as a 911 recording might be), the equation for determining the distance becomes: t=tb - ts= d/Vb- d/Vs If the muzzle blast duration obscures the sound of the bullet hitting the target, simple inspection of the sound waveform is insufficient. " In response to your request regarding this accusation against an LV Police Officer: You didn't have time to watch the video yet. Debunk it please. https://libertysflame.com/cgi- bin/readart.cgi?ArtNum=53025&Disp=78#C78 I found/took their formula, built a spreadsheet, and plugged in 223 balistic data generated via shooterscalculator.com: Important to note: * Presently we don't have information regarding specificaly which weapons and amunition were used. So the ballistic data was generated with a guestimate 223 configuration. * My DAW (Sonar) doesn't appear to have the capability of capturing a sound spectrogram like the ones the authors of the study produced; but after reading their commentary on the blast noise obscuring impact noise, I filtered the crowd noise, and filtered/looked alternately for the report and then the high energy impact sounds - and I revised T1 and T2 accordingly. More accurate results could possibly be obtained if the corresponding burst sequence on the Taxi-Driver video is identified and aligned, as the taxi-driver's audio contains only the muzzle blast and echo. It doesn't have the crowd and impact noise to obscure the muzzle events.
