Pace and efficiency are definitely linked, but I don't necessarily know that I think faster = more efficient. And there are folks mentioning stability, also definitely linked here, but i think max efficiency would lean more into stability than pace.
Linking pace with efficiency also seems to create the idea that "faster will be the winner" which, you know, that's a whole thing, introducing competition in an arguably healthy way.
I generally tend to find that emotion will usually come before logic. Building something that could be considered efficient, but a feeling says "This could be more efficient" and then logic jumps in and does the work.
Just some stream of consciousness writing here, food for thought maybe, or extremely poor quality ideas!
