Okay, as requested. Locking down the "tile" sizes, for those of you who haven't tuned that conversation out yet. It was a whole lot more work than I thought it was going to be. Keep in mind, I haven’t actually seen or measured the floors up close, so I’m unable to say whether they’re even tiles at all (bear with me on this). Jethro may have more specific knowledge of the exact material. I had been calling them a “tile grid”, assuming they were tiles.
Since the camera lens in the main hallway is a wide angle (determined by my lens correction diagrams), I have always been unsure of the aspect ratio. My video analysis focused solely on height estimates, so for those purposes, width estimates (including floor tile sizes) did not have to be accurate. I based previous estimates on an assumption using standard construction material sizes.
But...
Per request, I went back and studied several more photos off the Church pages. While I still cannot say for certain the grid is actual tiles
per se, I was able to get a bit more information about them and the size for my independent estimates. I found a couple interesting things out in the process. First of all, I believe the “tiles” may actually be scored/stained concrete. Let the debates begin!
The secondary hallways are stained concrete (which fits with what previous locals have maintained about the construction of Creekside being pretty spartan - in keeping with church values). That meant the grid may not be based on a standard size floor tile, after all. Additionally, if the measurements attained are accurate, the aspect ratio of the wide angle lens footage is different than previously thought. More on that later, but here's an image of what I mean:
For the measurements: Based on 4 church interior photos and three isolated frames from the surveillance video, I used ladders, door widths, door heights, table heights, and average person height approximations to calculate the grid size. From that, I was able to determine the repeating pattern of squares to be an average of 34” sq. This puts the diamond grid diameter at about 48” (√2 × 34 = 48)
So, measuring the floor as square tiles with diagonal Xs (laid square - as Jethro believes it to be), they are 48” tiles. As a stained concrete floor with a diagonally scored grid (which I believe it to be), the repeat pattern of grid square is 34”. While we may not agree on how the floor was laid or what materials were used, we came to the same determination with regards to the grid size - the important element.
The surprising result of that assessment is that now the aspect ratio of the oft-referenced MPD video is off by a factor of nearly 10%. This means after lens correction and aspect ratio adjustment, the wide angle footage from the main hallway would look something more like the images below, making the subject in the video about 10% taller or 10% thinner than many people are seeing.
