This video shows me visiting the Binance website and viewing the backend server data their page requests. Their page display rankings differ from the backend data. The backend data shows that f2b's score is 5.7, ranking first. 714's score is 5.700000000000001. According to the rule of lower score wins, f2b should win.

In addition, I noticed that there is other data in the API. I used their formula to recalculate the scores for f2b and 714:
The formula is:
Score = (Market Cap Rank × 30%) + (Price Increase Rank × 20%) + (Trading Volume Rank × 50%)
f2b's data from the API:
"market_cap_rank": 5,
"percent_change_24h_rank": 15,
"volume_24h_rank": 2,
So we substitute the data:
$Score_{f2b} = 5 \times 0.3 + 15 \times 0.2 + 2 \times 0.5 = 1.5 + 3 + 1 = 5.5$
714's data from the API:
"market_cap_rank": 2,
"percent_change_24h_rank": 24,
"volume_24h_rank": 1,
