Don't know where to put this other than starting a new thread:
Inflation is almost 6% yearly, and it's been less than a year. 6% × (8 months / 1 year) = 4%. (With percentages under 10%, differences between linear and exponential are insignificant.) However, most restaurants have increased their prices, and those increases are more than 4%. (Most restaurant price increases throughout the years are more than 4%; they're just not normally as frequent.) Are restaurant and/or food prices increasing more than other items, do I have a misunderstanding of the inflation rate, or it is confirmation bias?
