It seems that the data on the Dune website hasn't been updated today, and the Tip Allowance has nearly dwindled to zero. These details pertain to the date 2024/04/16. The pressing question remains: Will our activities be accounted for up to this day? No one seems to have an answer!

You are correct that they data is not updating since then, but that portion of code is not for that purpose, it's just saying that from that date the code will use 0.15 in place of 0.25 coefficient 
And that's the reason that from that date our tip allowance reduce by 40%!
