How much luck from recoding an existing Λ character?

Solution 1:

A Recoded character will inherit 100% of the original character's Luck value and 20% of the Luck values from the monsters used in the recode.

An existing "Λ" character will also gain an additional 5 Luck if the character is recoded again.

(Emphases mine.)

If I interpret the Terra Battle Wikia page on Recode DNA and Luck correctly, the current Recoded character should get 100% of the newly-Recoded character's Luck PLUS 5. So, in my example problem, it would be the second case ((10 + (50 + (50 * 0.2) + (50 * 0.2)) + 5) == 85).

Information from a reddit thread also seems to bear this out. Will update this answer when I finally decide to try it out (which may be a long time seeing as I am thinking of emptying the Pact of Fate pool too).

EDIT: Can confirm that recoding a character again will add luck using (new base char boosts) + (monster 1 luck * 0.2) + (monster 2 luck * 0.2) + 5; it will not exceed the max 100 limit for recoded characters though. Just did this with a Jaguna on top (+~103) of my existing Jaguna Λ (L 0.3).
