This is huge. Having a pick list is great and necessary if you happen to finish in a picking position (nobody wants to send somebody to the field where they are literally looking for the next ranked team or waiting for someone to text them the team number to pick), but a bigger benefit is for match strategy.
We have won matches we had no business winning because our scouting data helped our alliance determine the proper strategy for that match. During Steam Works, for instance, knowing how many rotors our alliance was capable of scoring allowed helped determine when to start shooting fuel (we were fast, but our accuracy was not real high. This was a “tie breaker” type of strategy in close matches).
In this year’s game, you can use data to determine if you can out score the other alliance or if you need to limit their score (play defense)? Can you get a ranking point by filling a rocket and do robots need to work together to achieve this? Is it possible to get a ranking point at the end for the climb (what level can each robot climb to and when do they need to start)? If your alliance can’t get a ranking point for climbing do the points awarded for climbing out score what they could have been doing if they continued to score hatches and cargo? Knowing how long it takes robots to do particular tasks and how successful they have been at doing it , is great for determining strategy. Imagine an alliance that has 3 robots that can score hatches and cargo in the Cargo Ship and the lowest level on the rocket, knowing who should be placing hatches vs. cargo based on success rate and speed can optimize your alliance score. Scouting data can tell you this.
