You only listed fights that were in season 1. There are plenty more fights where no-one is there to save Deku, for instance his fight with Muscular. Deku also doesn't need to think to maintain it. Once it's activated (which it automatically is in the beginning of the fight), he can just go and fight without thinking to keep it active, like All Might. You're also forgetting that Deku also has higher than baseline durability, so he'll be able to take attacks too, as well as keep on fighting for a brief period longer, since he has superior stamina.
