The truncated average removed the top 31% of the largest increases; isn't that just artificially beautifying the data? Core PCE is still rising, and playing data games for too long will eventually expose the truth.

Dallas Fed's trimmed mean inflation rate for April was 2.3% year-over-year, down from 2.4% in March, becoming the inflation trimming indicator emphasized by Waugh. However, several economists warn that this indicator may systematically underestimate actual inflation because it excludes the top 31% of increases and the largest 24% of decreases, such as rising items like gasoline and airline tickets. Core PCE for April was 3.3% year-over-year and continues to rise; Standard Chartered and Harvard scholars believe that the trimmed mean is difficult to reflect true inflation, and core PCE is more credible.
