Since the pandemic I've found the blue to be a lagging indicator, and if we're being honest the dollar should really be closer to $1,000 to 1, not $550. As Red said, the blue goes up, prices follow, but in the rare instances where it goes down, they don't follow it.
If you're like me you can check inflation in dollars via items you have purchased online and have receipts for vs today in pesos, and then use the dolar blue historico to check.
One common metric I use is a 1.75L of Coke Zero at Carrefour. It was $81 ARS (55¢ USD) when I moved back here in December 2020, and it's $523 (95¢) now. Almost doubled in dollar terms, and even worse in pesos. The dollar is only stabilizing vis-a-vis losing less when compared with pesos. This is why I tell people, sure, if you earn/retire in dollars here you'll be fine, but it's not like inflation doesn't impact you, it just impacts you less than 85% of Argentines.
