Tricky one, my sight glass is all over the place.
I added exactly 3.5 liters using measuring cup.
The sightglass was full when the bike was cold with (New Filter)< important fact as the filter is not yet filled with oil.

So I ran the bike to temp-220 and then shut off and recheck
while the bike was level on the ground and dead straight,
I noticed little oil near the oil filter and drain plug so it was confirmed to be
pressure due to too much oil > but when I checked the sightglass
this time the marker was at full as it should?!?!

Anyways I decided to play it safe, I drained about 1.5 to 2.0 liters out
and rechecked it was low after running the bike and shutting it off (At low marker or just below it).

I added 1 Liter exactly checked and added 1oz of oil each time and after running the bike the sightglass
filled up to just below full.

The trickiest oil change I have done to date and this is coming from a Ducati guy.

So as the OP suggest with the addition of fill it up to 3.0 Liters ONLY (if using a new filter or without new filter)
and check the sightglass after getting the bike to temperature where the
(Fan kicks in) shut off and check and add as needed.
It is an advice take it or leave it

Just my opinion, but I think you're making a big project out of something that is not that hard. And I would never run a bike 2 liters low of oil (which is about half of capacity) to incrementally add some back trying to find the exact amount to put in.

Maybe I've been lucky, but I've had zero problems doing oil changes by simply draining, changing the filter, and adding 4-qts back in. Go for a longish ride, put on stand, and the oil level is right at the top of the sight glass where it stays, more or less, until the next oil change.

You might be right and it just might be that simple, the point is
to avoid having to take out oil and as an added assurance use 3.0L
and add to it from there as the oil is hot and should give accurate reading.

If you're going to take this approach of underfilling to begin with, I'd suggest a half-liter under spec, not a full liter. Personally, I wouldn't want to be riding a bike that is deliberately a full liter low.

Just want to update this thread a little. My 2012 did come with the 779 filter from the factory.

I went to change the oil today and I found out that the filter they put on when they did the recall was the 541. When I opened the box for the new filter I see it is the 779 - so which is the correct one?

Both work fine. The first post of this thread discusses the difference.

Luckily a screwdriver will stab through either one, so getting it off won't be a problem
