Why every figure is cited
Every calculator on this site links directly to the government order, notification, or gazette Schedule its numbers come from, with the date it was last checked against that source. Where a figure couldn't be independently confirmed, it's marked "needs manual verification" instead of being silently presented as fact — you'll see that flag on the source panel of any calculator, not just in a hidden changelog.
This is a solo-maintained reference tool, not an official government resource — see the footer note on each calculator for how to treat its results.
