Automatically updates ONCE per day at 00:00 UTC (possibly offset during daylight savings)
Formatted to nearest 100 to reduce likelihood of display in scientific notation, and also to avoid false precision

Regarding rounding[edit source]

if rounded to nearest 100-thousand, will often display in scientific notation
if round ends in 5 zeroes, there is an intermittent sci notation problem
This CAN happen even if the number is rounded to 0 places - IF the number ends in 5 zeroes
results are inconsistent, seemingly dependent on which server renders the numbers
