Trying to calculate a change over time, but ignore missing data

Formula: =IFERROR(ABS([2012]@row - [2023]@row) / MAX([2012]@row:[2023]@row), "")

but the formula returns a 100% if the first column data is missing. If the last column data is missing, the % change is skewed lower.

The data is not restricted or proprietary. it is new construction cost by zip code over time.
