Here is how I see it.
A lot of people want to move yoyoing away from speed and start encouraging innovation and performance.
The best way to encourage innovation and performance is to make these two things win contests.
The question is: what system will make those two things win.
The tech cap is suggested because it is supposed to be better than the current system.
The tech cap makes it so that top competitors will often tie in tech, making the tie breaker preformance.
The only way innovation would be encouraged by this system would be if the judges take innovation into account in the performance categories.
The system might even discourage innovation because people may play it safe and do generic, easy tricks to get high cleanliness score.
