For each release, we went through the content we introduced and estimated either how much power it gave characters (Mastercrafting or extra Ascendancy points, for example) or how much faster it let characters find items.

It's certainly subjective. But even with ballpark values, it shows the compounding effect of players having far more ways of stacking up damage (or getting to that damage) with each release.
