Not necessarily. The moving recorders add significant error, but if you focus on the stationary recorders I think you will see there is very tight agreement for the locations of shots 1-8. You don’t want to use the Cruiser video? That’s fine. Instead, use either the NTD press riser video or the “Don’t Run. Don’t Run.” video. If you use one of these, along with Ross and Podium, I’m confident that you will change your mind about shots 1-3 and 4-8 being from different locations. And I am talking about using boom times for these shots, not corrected crack times.
Using this data, the first 8 shots fall within a 4 foot radius:
I am now using leading-edge boom times as much as possible in my analysis, as shown by the color coding in the spreadsheet I placed on Brian’s file server:
For the Podium, I had to estimate the boom times for shots 6 and 7 because they were covered by cracks. With the audio waveform analysis that you do, you may be able to get better timestamps for those two shots and tighten up the group even more!
