Surprisingly, yes it does Help Him!

Shisui and Naruto spent two hours training together, and Naruto really improved! His Technique with Shurikenjutsu was now satisactory to them both. ''You did well kid, I'll have to check in with you every now and then, cause from now on: YOU AND I are Rivals! Never forget ahat your fighting for, and those around you won't forget what they are fighting for either! I hope to see you again, hopefully not in battle, but listen I have something for you. In this scroll is a list of Techniques on how to Improve your Basic Skills, I think you'll find that Improving the basics greatly inscreases the Strength and durability of a simple technique. And if you complete I'll come back with another one for you. Just remember to never stop practicing on what you think you know.'' Says Shisui as he disappears to get some sleep.

He wakes an hour later and decides to shower for ten minutes before he cleans and sharpens his swords.

He then reports to the Prelims arena and waits for the doors to open.
