Reflexes don't increase or decrease Evasion bonus in Codex

[Off The Record]

I was installing and uninstalling Sabrae's cybernetics to look into what the stats actually increase. Reflex Turner didn't change my Evasion rate from 21%. So I cracked open a save editor and reduced my Reflexes stat to 15 and gave myself 50 stat points so I could compare the before and after. Whether my Reflex stat was 15 or 65, my Reflexes stat remained 21%. In contrast, equipping/removing gear that gave me an Evasion bonus changed my Evasion bonus in Codex. Is it normal that I can't see the effect of my Reflexes stat on my Evasion rate in my Codex?

While Evasion and Reflexes are added together in the to-hit calculation, they are separate stats.
Given that Evasion is capped, it's actually more beneficial for you this way.

(Physique OR Aim)/2.5 + Accuracy vs Reflexes/2.5 + Evasion.
