There really isn't much good about this system.
You could do that, or you could kill faster and keep the chain bonus alive.

Yes people could slowly kill a monster, but they would receive approximatively the same SP as if you fought at a normal pace.
It wouldn't be the pace of the battle that gave you an increase in SP, rather it would be fighting more difficult battles that would result in the most significant SP increase.
