Check chapter 410. One of the pages shows a clot of energy, which symbolizes the sage - a man who has reached a balance of energies. The balance is reflected in the picture. A perfect Sage has perfect balance.

Look at all the information in the manga. Jiraiya, and Jugo are capable of Senjutsu despite the lack of proper balance. Jiraiya's situation is explained in the exact same chapter you cited.

Also in that chapter, on the same page you cited no less, are diagrams that show how grossly misporportioned the energies have to be in order to face the worst effects of "too much" or "too little"
