My advice is to never, EVER level up your BB/SBB until your unit is at max rarity. This is because every time you evolve your unit, the BB/SBB level drops by half. It is much more efficient to only level the BB at max rarity so that you only have to use 18 Burst Frogs to level up your BB from Lv.1 to SBB Lv.10 or UBB.
