These numbers won't be accurately comparible.

Different suspension manufacturers (H&R/Bilstein/Vogtand/Eibach/Tein/etc.) use different methods to develop their lb/in figures. While at least two of those manufacturers use [Lh2 (load rate at loaded height minus 10mm) minus Lh1 (Load rate at loaded height)] divided by the diffence between the two heights (10mm) ; I know not all of them use that formula.

Therefore, any comparisons must take into account the different methods used to gather the data.
