Ummm ... okay ... aside from the fact that the <br/> and <span> within an <h1> makes for some pretty ugly code I think we're talking about different kinds of subheads.

This is my HTML/CSS:

Spoiler:

<h1>Chapter 1</h1>

<h2 class="subch">Subhead AAA</h2>
<p>text text text</p>
<p>text text text</p>

<h2 class="subch1">Subhead BBB</h2>
<p>text text text</p>
<p>text text text</p>

<h2 class="subch1">Subhead CCC</h2>
<p>text text text</p>
<p>text text text</p>

<h1>Chapter 2</h1>

<h2 class="subch">Subhead DDD</h2>
<p>text text text</p>
<p>text text text</p>

<h2 class="subch1">Subhead EEE</h2>
<p>text text text</p>
<p>text text text</p>

<h2 class="subch1">Subhead FFF</h2>
<p>text text text</p>
<p>text text text</p>

h1 { font-size: 150%; margin-top: 20%; margin-bottom: 1em; text-align: center; }
h2.subch { font-size: 120%; margin-top: 0; margin-bottom: 1em; text-align: center; }
h2.subch1 { font-size: 120%; margin-top: 2em; margin-bottom: 1em; text-align: center; }

Then I run it through Calibre with the following settings:

• Structure Detection > Insert page breaks before: //*[name()='h1']
• Table of Contents > Level 1 TOC //h:h1 Level 2 TOC //h:h2

With the above, Calibre inserts a pagebreak before each chapter but not before subheads and it creates a TOC structured like so:

Chapter 1

• Subhead AAA
• Subhead BBB
• Subhead CCC

Chapter 2

• Subhead DDD
• Subhead EEE
• Subhead FFF

I think it will take a lot more (ugly ) code to make the eschwartz method accomplish the same
