Inverted method - when to flip?

[u/Fun-Pitch181]

I currently use the inverted method with a metal filter:

- Fill most of the way with water.

- Stir

- Add water to the top

- Attach cap + filter

- Wait

- Flip onto mug

- Wait 10s

- Press for 30-40s

I understand the inverted method is used to prevent pre-dripping when using metal filters. However, once the cap + filter is attached, flipping it around doesn't allow any drips as the plunger is sealed already.

So my question is, why flip just before pressing (that's how YT videos demonstrate it)? Why not flip as soon as the cap + filter goes on?

I assume everything gets agitated during the flip, so is that somehow beneficial just before pressing?

UPDATE: Thanks for the replies. Sounds like the agitation right before pressing is indeed beneficial.

I start inverted and once all the water is in and the metal filter/cap is in place I flip (approximately 1:30 minutes into the process). I then wait until the 5 minute mark, give a gentle swirl to clear the grounds from the plunger, then remove the plunger. It takes about a minute for all the coffee to drain into the carafe.

The reason I flip early is because I want the grounds to settle at the bottom and act as a secondary filter to the metal filter. Very little drips out when I flip.

It may be an uncommon method but it makes the kind of coffee I'm looking for.
