I went over both stage and bleachers numbers again. Actually, up to now schroederized made the most accurate drawing in his post 160 in topic 40703:
Below you see his drawings. He also estimated the stage hight at 48 Inches. What he did not get right was the floor height of building 6, of which we are all clear on now (1335). One thing that he did draw our attention to is that the speedy bleachers are on wheels in the middle of the stage which gives us a 1336 height instead of 1335 (which is the height of the corner of the bleachers) See Google Earth Pro confirmation below. What schroederized did not at all take into consideration is that when installing the bleachers they put wooden riser blocks and crank up the stage to stabilize. There is a good video here where you can see the wheels in the middle and the way the crank up the stage to stabilize it:
Up to now we have added 4 inches for this preload. Giving Crooks the benefit of the doubt of I am willing to decrease this number from 4 to 1 Inch. In addition, I put the stage from 45 Inches to 48 Inches also giving Crooks the benefit of the doubt. I also took the impact postion from schroederized moving it from -3 to -4.152. So, we have pushed the numbers in favor of Crooks. Please have a look at the new Excel table. If everybody agrees with these numbers, I will back trace the bullet accordingly.
