ok, when my rear looks like that its usually just a bit high, or I am being too aggressive but either way the bikes eating a lot of rubber

Good question.
This is the first year I use them in a V4.
For the moment, I can't express any particular issue.
They are reasonably good.
I am sure, that I wouldn't be able to ride 44 low in a Pirelli that worn out.
They were still rideable and gave a lot of feedbacks.
The reason of that bad conditions were multiple, and not due to the tire itself.
The new set were very straight forward, maybe they need a little more carefulness to warm them up and keep them warmed, but nothing else.
This is the condition at the end of the day, with around 25 laps.
I will do a comparison with Pirelli as soon as possible, since this was my first time with this bike, in Misano, so I cannot make any side-by-side comment.
According to a very fast rider ( I don't want to mention his name, because of NDA ), Pirelli should be faster ( 1 second in Misano ) in the first thermal cycle and then decrease to the same level at the second cycle, on a comparable compound.
My 2 cents

Until nobody's paying me, I am slow and I bet it won't happen anytime.
Today I rode with Iannone, Sam Lowes. Ferrari, Foggia and Antonelli.
This are FAST riders

2022 and on base is default set at -1?
Do i understand correctly that going from -1 to +1 raises the swingarm pivot thereby increasing anti-squat?

So NO charge for the vital piece of exact information........whist other alleged esteemed racers talked bollox around this topic I can confirm
the 22> base fixed location is the same as the -1 position on the 23R. I fitted the eccentric SA pivots to my base and measured before and after.
The mountings in the crankcase are in the same position.
for the previous 18-21 non R bikes, the mounting in the crankcase is lower so if you fit the adjustable pivots to them and turn them right around to +3 indicated on the mounts, it is actually only in the position of the -1.

Good to know.
And do i understand correctly:
1. that going from -1 to +1 raises the swingarm pivot?
2. The increments are in mm, so -1 to +1 raise the pivot 2mm?
So are the early bikes at -1 or are they something lower yet as delivered? I thot the pivot change was 4 mm up and they shortened the dogbones 5mm which raised the rear and raised the front also. So an anti-squat and CG change? I wanted to raise my pivot and was going to buy the eccentric parts. So can I gain pivot height by adding the eccentric to the early cases? Thanks.

Anti squat relies on a ton of factors including the eccentric position/wheelbase, preload, rake, ride height, etc so to basing your settings to someone else's setting is kind of pointless.
The 22+ V4 SAP is 4 mm higher the 21 bike. And with the 23 R you can potentially increase it another 4 mm. So it sounds like the with the 23 R you could potentially be 8 mm higher (at the +3 setting) than the 21 base or 4 mm higher than the 20 R. The 23 R SAP can go 4 mm higher than base or 2 mm lower.
Pirro's 23 R SAP should be 2 mm higher than the 22+ base model. Also of note, the 23 R default setting is +1

As I understand it the SBK bikes and certainly the MotoGP bikes have a single button on the bars that changes engine braking with the push of a button, and the riders at that level often change the engine braking map several times per lap, depending on the corner. My RC 8C is like that, you can change the TC slip amount, the EB, and Wheelie Control all with single button pushes without toggling through screens etc. so you can literally change all that stuff corner to corner if you are an advanced enough rider.
Would be useful if Ducati set it up like that.

Ideally
What bike is it?
Is it the std swing arm?
What length is it pivot to hub centre?
What ride height is it in the corse tool?
What rocker?
What shock length?
What length dog bones?
What have they done with the front?
What fork free length?
What fork height?
What rake?
Any insert offset?
What yoke offset?
