5.4 enchancement scaling = damage reduction?

[Tellana]

i have 40 crit gems(tooltip) on lvl 71

but all crit values (gems, items, enchants) together are much higher than the summary list shows. Im little bit confused

Here's a list of enchants I compiled to show how they scale at different levels: http://goo.gl/YfnWs

The PTR hasn't been up long so these could all change before 5.4 goes live.

all information which i found in column 80, I got already with level 71 on PTR.
