I think everyone would benefit from discussing how to "master" Bo1. This is a much more friendly and constructive topic to discuss. Anyway, if you are prepared for Bo1, then you are more than prepared for Bo3 (If it hypothetically came back).
So what are some ways to master Bo1?
Murphy's Law: "Anything that can go wrong, will go wrong [especially in the finals match]"If you notice something go wrong when you are practicing, you should take note of it and make sure that it does not happen again. If you want to go a step further, you can look at how other robots might fail, and modify your robot so that it does not make the same mistake.
Strong communication between your team and your alliance partner. In some of 5225A's matches you can see their driving coach advising their partner what to do. That is key to having an alliance rather than just two teams scoring the same color.
Adapt to your opponents: every alliance is going to be different. Time should be taken to "learn" your opponent and develop a strategy accordingly.
Please feel free to add more to my list :)
Next, On the note of strong/poor judging:
I think that teams should take advantage of the QNA and post precedents of scenarios that happened at regional or state tournaments so that the GDC can give an official ruling. I am pretty sure that the incident with 127X was not the first time a robot tipped another robot over during autonomous of a regional or state tournament. Maybe if it was asked on the QNA then there would be a definite response before worlds and people would not argue about the ref's ruling. This relieves some of the stress on the ref too.
"Also, if anyone wants to tell me how I should have changed 127X to be untippable in this kind of situation while still being at all competitive, I'd love to hear it! I thought we did our best at that."
I think that it was a bold attempt to go for that third cone, but to be completely honest, I have seen so many robots collide when they go for the same cone. I would have avoided this cone all together, and opted to go for the autoloader instead. Notice how points 1 and 3 from above perfectly apply to this situation. I think that this serves as a learning experience, and want to congratulate you for making it that far at Worlds. :)"
