I know specs go by full cycles. I was always taught not to shallow charge because each partial charge essentially carried some overhead to it. Sort of like two 10% is not equal to one 20% charge. I guess that's not true anymore since I couldn't find anything on it.
Looks like maybe I was thinking of the lead acid battery "formatting" phase. Seems as though lead acid batteries benefit from deep cycles with full charges, while lithium batteries benefit from smaller depth of discharge without going to full.
