How out of possibly hundreds of different operations that could take the hex table and and that date in possibly 5 different date formats as arguments, would you find out that it's shift key and YYYYMMDD?
(I would never in a million lifetimes have guessed that bip thing. How do people even know this?)
Looking at 426 252 813 1535 1935 1603 1068 1479 1168 756 878 1083 I sure as heck would not think, oh that's bip39 indexes.
