When it comes to number-crunching at the Olympics, the attention has all been on the medal tally, but now funding is front of mind.
It's divvied out based on results, which has the women's Black Sticks coach worried after placing fourth for a second Olympics in a row, and future Games are looking more expensive than ever.
Tokyo 2020 is set to be quite the show. Kiwi athletes are already turning their thoughts to the next world stage. Black Sticks coach Mark Hager says being in contention depends in part on competing with other countries' funding.
"If I look at someone like Germany or Holland or Great Britain - the teams that we're vying against - most of them are full-time programmes; they're doing hockey 12 months of the year," Hager said.
"We do hockey 12 months of the year, but they're working and studying on top of that, so it may be that that's the difference between us and winning a gold medal, or a silver or a bronze."
Bronze medallist Tom Walsh says funding from High Performance New Zealand was key in his performance.
"[In the] last few years, things have really changed for me. [I] started to get a lot more help and stuff and, you know, for example in America, if you're not in the top five in the world for track and field you don't get funded whatsoever," he said.
It's not just athletes battling the books; the $2.7 billion Tokyo Stadium design was recently ditched after local protests. The Rugby World Cup final was also meant to be played there, but will now be moved.
Still, Japan has set aside $5.4 billion for Olympic infrastructure. And with that high investment, expect a high-tech Tokyo Games.
They're also tripling the amount they're spending on robots over the next four years. They've got some in development now, which at the Games will help spectators carry their luggage, hail taxis, drive cars and act as translators.
Then there's Japan's huge grassroots investment in a programme called Sport Tomorrow - nurturing young talent over the next four years and bringing in elite coaches from around the world.
One of the leaders of the government programme tells us that many Japanese officials and companies are in Rio now researching how to make 2020 a bigger success.
There's already a long history of co-operation between the two countries, with Brazil home to the largest community to people of Japanese origin anywhere in the world outside of Japan.
In Tokyo it's all about the future - and the future looks expensive.
