Different number of sub-levels in different chapters?

Question

Is it considered bad form to have a different number of sub-levels in different chapters in a technical report? Or would something like the following be admittable? > Chapter 1 - Introduction > > Chapter 2 - Theory > > Section 2.1 - Explosions > > Section 2.2 - Drag Loads > > Section 2.2.1 - Drag Loads on Piping > > Section 2.3 - Compressibility Effects > > Chapter 3 - Simulations > > Section 3.1 - Stationary Simulations > > Section 3.2 - Transient Simulations > > Chapter 4 - Conclusions And, do each heading has to be followed by text, as in the following? > **Chapter 2 - Theory** > > In this chapter we will consider... > > **Section 2.1 - Explosions** > > Where I work, we try to stick to the [IEEE Style](http://www.york.ac.uk/integrity/downloads/15663_IEEE%20Style-webFINAL.pdf), if that in any way affects the answers.
