If you mean the chart in post #14, it gives percent increase between cogs, by larger cog divided by smaller cog for each step. It doesn't show the same percentages between IGH ratios, but I calculated the same way for each cog, range 2 divided by range 1, and range 3 divided by range 2. And I'm getting 33% in both cases, much bigger than the cog steps, and bigger than 52 over 42 which equals 24%.

I have respect for you based on great answers I've seen from you on many topics. On this, I still can't see it, but perhaps there is something I am missing.
