Question on the tolerances of High Goal Height

I was wondering why the tolerances for the High Goal Height are +/- 1"? Seems quite extreme for the center piece goal of this year’s game.

That is the standard tolerance quoted in the game manual for just about everything.

Expect the actual measurements to be much closer to the quoted figures in almost all cases, especially things like the goals that are hard-mounted to the field.


I think the OP was asking why it specifically points it out on that one measurement (the 25") on the diagram, and nowhere else, even though they are all subject to the same tolerances?


My gut is VEX wanted one reference point that would be the place to check the field assembly to be within ±1" and enable shooting into the basket. Otherwise you will have cumulative errors propagate, so if the center pole is slightly tilted and one side is ±1" relative to the 25" reference, it would be ±2" relative to the field. It is a compromise of imperfect world. This avoids having to explain to teams that the top plate of the goal can be way off, only the basket matters to accomplish the high goal scoring task.


My take on the illustration is that the “basket” part of the high goal might be made of a slightly flexible plastic, so it might have a tendency to not stay exact; therefore, the game manual dimension was placed to remind you that the basket might not be a perfect 25". I don’t expect it to be floppy, but if it comes in at 24-1/2", for example, the referees wouldn’t have to be futzing around with it to try and get it perfect.


Think it is just a simple case of the goal is the most important part of the entire setup.
The rest of it doesn’t really matter, as long as the goal is within the tolerance as specified.
