I've checked my RE'ing results again for both MK-1 & MK-2 earpieces and MK-2 implants and my results have been consistent.
Using the Frasium Closed Circuit Energy Chip as the base Green:
Strength 172, Endurance 177, Critical 84, Surge 79
RE to Blue improves the primary stat strength to 199 and endurance to 205 (Pri +27, End +28)
The three blue derivatives are Expert, Fervor and Veracity which give
Expert (Power +14, Surge +12)
Fervor (Accuracy +12, Critical +14)
Veracity (Defense +14, Shield +12)
RE of the Blue to Purple improves the primary stat strength to 222 and endurance to 231 (Pri +23, End +26 relative to the Blue)
Expert gives three purple derivative which are Expert, Hawkeye and Vehemence
These changes in the prefix give
Expert (Power +13, Surge +11)
Hawkeye (Accuracy +23, Power +13 but you lose the Surge stat (-12))
Vehemence (Alacrity +23, Power +13 but you lose the Surge stat (-12))
Fervor gives three purple derivative which are Endowment, Fervor and Supremacy
These changes in the prefix give
Endowment (Critical +13, Surge +23 but you lose the Accuracy stat (-12))
Fervor (Accuracy +11, Critical +13)
Supremacy (Alacrity +23, Critical +13 but you lose the Accuracy stat (-12))
Veracity gives two purple derivative which are Shielded and Veracity
These changes in the prefix give
Shielded (Absoprtion +27, Shield +11 but you lose the Defense stat (-14))
Veraticty (Defense +13, Shield +11)
The clean version is:
Green RE's to the following Blues
Expert (adds Power, Surge)
Fervor (adds Accuracy, Critical)
Veracity (adds Defense, Shield)
Blue Expert RE's to the following Purples
Expert (adds Power, Surge)
Hawkeye (adds Accuracy, Power, loses Surge)
Vehemence (adds Alacrity, Power, loses Surge)
Blue Fervor RE's to the following Purples
Endowment (adds Critical, Surge, loses Accuracy)
Fervor (adds Accuracy, Critical)
Supremacy (adds Alacrity, Critical loses Accuracy)
Blue Veracity RE's to the following Purples
Shielded (adds Absoprtion, Shield loses Defense)
Veraticty (adds Defense, Shield)
Again, I have yet to find evidence of a third derivative for the Blue Veracity.
