Does the Disheartening Display Feat enhance or replace the effects of a Dazzling Display?

[Aresirn]

When Dazzling Display is used on a target, it inflicts the Shaken condition for a number of rounds depending on how high the demoralizer rolls above the target's DC. Following the Demoralize rules, it makes sense that if Dazzling Display is used on the same target again, it would suffer additional rounds of Shaken, extending the duration of the effect.

But what happens on that 2nd Dazzling Display if the demoralizer has the Disheartening Display feat?

Are any additional rounds of shaken that would have normally been caused by the 2nd Dazzling Display ignored in favor of just upgrading the fear effects the target already had?

Or are the previous rounds of shaken upgraded to frightened, then the new rounds of Shaken added on after the upgraded old effects?

Or does the 2nd Dazzling Display increase the duration of Shaken from the 1st, then the Dishearten effect upgrade all those rounds to Frightened?

We've got 2 players that are planning to use Demoralize, so I'm trying to make a google sheet for our GM that will make calculating and tracking all these fear effects easier, but I need to know exactly how they work before I can make the sheet accurate.

Demoralize:
"If you are successful, the target is shaken for one round. This duration increases by 1 round for every 5 by which you beat the DC. You can only threaten an opponent this way if it is within 30 feet and can clearly see and hear you. Using demoralize on the same creature only extends the duration; it does not create a stronger fear condition."

Dazzling Display:
"While wielding the weapon in which you have Weapon Focus, you can perform a bewildering show of prowess as a full-round action. Make an Intimidate check to demoralize all foes within 30 feet who can see your display."

Disheartening Display:
"When you successfully use Dazzling Display against any shaken, frightened, or panicked opponents, their fear increases by one step. An already panicked creature demoralized by this feat cowers. Once affected by this feat, a creature cannot be affected by it again (by you or anyone else) for 24 hours."

Basically the first time you use Dazzling Display against a group of enemies, you would Shaken them, but also any fear steps currently on them increase by 1 step. And this increase of 1 fear step can only happen once per every 24 hours per individual monster/NPC, but you can continue to use Dazzling Display to reapply Shaken all you want. So in other words you can continue to use Dazzling Display against them, but it's not going to keep increasing Fear by 1 step your 2nd, 3rd, 4th time, it's only going to reapply Shaken each subsequent time you use Dazzling Display.

So ideally, you'd let any PC who can Shaken/Frighten/Panic go first, and THEN your PC with Disheartening Display use his Dazzling Display to increase any existing fear effects by 1 step.

Sorry, I didn't do a good job of phrasing my question, let me try posing it in formula terms.
If a Demoralizer with Disheartening Display makes 2 successful Dazzling Displays against the same target, which of these is the correct way to calculate the results?

1. (Shaken from 1st Dazzling Display[Turn 1] x Disheartening Display Upgrade[Turn 1]) + Shaken from 2nd Dazzling Display[Turn 2]

2. Shaken from 1st Dazzling Display[Turn 1] x Disheartening Display Upgrade[Turn 2]

3. (Shaken from 1st Dazzling Display[Turn 1] x Disheartening Display Upgrade[Turn 2]) + Shaken from 2nd Dazzling Display[Turn 2]

4. (Shaken from 1st Dazzling Display[Turn 1] + Shaken from 2nd Dazzling Display[Turn 2]) x Disheartening Display Upgrade[Turn 2]

It's just Shaken from 1st Dazzling Display, and then reapply Shaken from 2nd, 3rd, 4th Dazzling Display. It's not meant to worsen its own shaken effect, its meant to worsen a party member's fear effect. Tbh, this feat is poop, that's why hardly anyone ever gets it. Dazzling Display is horrible enough already, and honestly the only reason people get it is because it's a feat tax for Shatter Defenses <--- which is actually useful.

On a Player Character these feats are definitely poop, but I'm planning on shooting arrows from horseback, so I'm giving my Bonded Mount animal companion the intimidation feats so they can do something useful without having to go into melee.

Also, there is at least 1 other player on our team who's taking Shatter Defenses, so having my companion pre-demoralize for him will save him some actions.

You can give Companions a very good intimidation bonus very early by combining:
-Evolved Companion (Skilled: Intimidate) [+8 Racial bonus to intimidate]
-Ferocious Beast [Replace the horse's usual -2 charisma modifier with 1/2 their master's class level for intimidate].
-Aberrant Archetype [Makes intimidate a class skill]

In any case, the text for the Disheartening Display feat says that it increases the fear effect of any shaken, frightened, or panicked opponent by 1 step. I've not seen anything to suggest that this does not apply to the shaken effect caused by a previous Dazzling Display (assuming you can beat the target's DC by enough with the initial Display to get more than 1 round of shaken) though I don't mind being proven wrong if you can direct me to a source that says otherwise.

Actually with 1 level of thug rogue dazzling display is amazing. Extra good if you take 2 Cavalier levels (order of the cockatrice) and can do it as a standard action.
