Before I read this article, I had a question in my head "Does after limit break the skill level will still increase every 5 levels like usual?" So I did a little research myself.

I had a maxed (lv.50) Azuki and 4 lv.6 (Azuki + 1 crystal mag) others. I remember her skill was at lv.13 before LB, and now at lv.60 + 4 LB, her skill is at lv.18. I expected 6 skill level increase (4 duplicates, lv.55, and lv. 60), but only got 5. I suspect the culprit was one of her duplicate fusion, which brought her from lv.54 (or 53, I forgot) up to to lv.56, but the level only increased by 1 (either from the duplicate or lv.55 increase, but not both).

My conclusion is if you plan to do LB before the card fully leveled, it's best to avoid fusing duplicates (or possibly also DLR) near the 5th level. But if you will transmigrate the card, I don't think it matters, the skill level after transmigration will reset anyway. But of course, better safe than sorry.
