I think it would be more efficient if he had skipped this "Second Step" of training: (sending Jutsus). Please correct me if i am wrong. By going straight to the "Third Step" of the training: (sending Shadow-Clones) he could gain experience faster, as seen in the previous chapter. And after the clone fail the transportation and sends the chakra back it should be less "chakra-consuming" than the Second Step.
