Our race pace in Saturday's Sprint after being out of position in Sprint Quali also provided the team with reasons to be upbeat about the road ahead.
Lessons were learned.
Whereas in China two weeks prior we weren't able to make the most of the new Sprint weekend parc fermé rules, Miami demonstrated a step up between the two sessions on Saturday before the Grand Prix on Sunday.
Lewis spent the final stint locked on to the rear wing of Sergio Perez's Red Bull, keeping the Mexican in his sights all the way to the flag.
Those up ahead were also in view, demonstrating clear progress from much of the opening five races prior.
"It [Sunday] was a good day," said Lewis after the race.
"It was a really great job by the team. I was happy with the set-up; I am glad we finally got that sorted and into the right window.
"To move forward and have some great battles was fun."
Toto also saw the positives. Acknowledgement of where we are will provide the best baseline from which to build from.
"Accepting that this is the pace level at the moment and then just carrying it over into the race is not something to be proud of, but it is a step in the right direction," he said.
