For lumber, data at [1] indicates much volatility in North American lumber prices from January 2023 to February 2026. Trough-to-peak prices for 2023, 2024 and 2025 have been over 30% across a given year. The main difference for 2026 so far is the stability of prices which have remain peaked for half a year.
Now is the perfect time for someone being overly dramatic to say "In the 2 years since July 2024, lumber prices have increased 47%, significantly higher than inflation".
But someone else could also say "Lumber prices are the same as July 2025 even though inflation has risen" or "Lumber prices are up just 10% in the 3 years since July 2023, lower than the rate of inflation across these 3 years".

Do you have a graph that extends to 2020?
https://tradingeconomics.com/commodity/lumber
Roughly ~400 index pre-Covid. Roughly ~580 index the past year. 45% inflation, compared to 30% reported inflation by BLS from October 2019 to June 2026.
So yes, lumber prices are definitely beating inflation.
Not sure what you were trying to say by playing around with the numbers in the last 4 years.
