I forgot the camera tonight, but I did do some playing.

The first thing that needs to be clarified is what to measure. After a minute or two to testing it was obvious that measurements could vary. I originally thought that the 6" measurement would be from the center of one clover to the center of another. There are however, multiple points to measure from.
ALL MEASUREMENTS REFEREED TO ARE FROM CENTER TO CENTER OF THE CLOVERS.

Second, the tetras I was using are PVC with aluminum clovers and/or steel clovers. The goals are also PVC with steel clovers. The goals start to bend in wards when 2 or more tetras are placed on them.

So, stacking 2 tetras sideways (like the STJB) was virtually impossible to get within 6". The closet we could get them was 6.5" with a lot of pushing and forcing. Typically the tetras were 7-8" for the closest tetra and 8-10" for the second. A tetra placed on top of the 2 sideways tetras wasn't even close to scoring, typically 15-18" away from the apex of the goal.

I could not see how any of the apexes of the tetras in the STJB are with 6" of any other tetra apex. Again, the biggest factor seems to be where the measurement is taken from.
If you are measuring the two nearest points on each clover, than the lowest tetra in the STJB is 5-6.5" from the apex of the goal.

I hope this helps some. I encourage everyone to test it out yourself and take some measurements. Also, before doing this maneuver in competition, ask for clarification from the referee. They will be happy to stop the problem before it starts.
