I learned clicking on an answer after getting it correct will move onto the next question faster compared to waiting for it. The total rice count does update in the servers, even if if it doesn't visually (refreshing the page will update the counter).

Rice count from 19,630 to 20,130 Time starts at 12.150 (first frame answer box begins turning green, since the total didn't visually update) and ends at 4:49.850 (first frame rice total is 20,130) at 60 fps to get a final time of 4m 37s 700ms.
