Thanks for the data point Brandon!

So the 25" was maintained, but they may have been firmer than what we got in our KOP.

In the kick off Video they say about 25", but the indicator was zipper functioning, and seems not bursting. I would say that both of these indicators are Pressure based.

Now we are at week 1, and the control is now sized based, it will be close to 25" ring, string, or hole in plywood.

This seems to be a significant change in the criteria for a "playable" game piece.

As there really is no governing body of the game piece, (i.e. official size and weight, like baseball, basketball, etc.) Sportogo publishes no tolerance specs on their ball, we should anticipate game piece variance in our design, that is part of the challenge.

We purchased 2 additional game balls, and did size and weight measurements on the 3 balls we had access too. We also contacted sportogo and asked about their ISO quality system, and what determines a sellable ball vs. an unsellable ball. This was never responded too, but review of the website, showed no mention of a ISO standards or a quality system, so we determined that the design should expect deal with large variance in ball diameter.

We also under inflated and over inflated our balls during testing, based on the video.

What we did not do, and what is being done at the events, is to do whatever it takes to get the ball to be 25".

That is what I think is happening, so a cover that is slightly under sized, is now being "overinflated" (by video terms) to meet a 25" size. The pressure of this ball is significantly higher, which will greatly impact the ability of may intake systems to function as designed.

As another side note, and I did not see which event I was watching at the time, but I noticed that none of the balls had the FIRST logo on them, like the KOP balls we received.

Did anyone else notice that?
