Which metric of inflation are you adjusting it to? And which assumptions are built into the goods and services measured, as well as their respective weights, of that index?

That's a false dichotomy. An imperfectly measured inflation adjustment IS STILL VASTLY SUPERIOR to a non-adjusted number. By an enormous amount.

How do you even measure inflation accurately, given the current government, and has there been 61% inflation over the last 5 years?

Economists exists, we have data on this. Don't be silly.
