Inflation readings being higher have nothing to do with a higher count.

Exact same amount of data points for inputs as 2% inflation.

It’s not about the amount of measurement points, uncertainties in dollar amounts tend to scale as sqrt. When you error propagate that you see that inflation uncertainty scales with inflation.

Very simple model

Inflation=v1/v2

D(inflation)=sqrt((D(v1)/v2)^2+(v1/v2^2 D(v2))^2)

Suppose

D(v1)=c sqrt(v1)

D(v2)=c sqrt(v2)

D(inflation)=c sqrt(v1/v2^2+v1^2/v2^3)= c sqrt(inflation+inflation^2)/sqrt(v2)

So can be seen that the leading term for uncertainty in inflation is linear with inflation.
