You should not mix
Can you mix DOT 5 and DOT 5.1? Despite having almost similar names, you should not mix the two as they have totally different chemical components. The DOT 5.1 is gylcol-based, while DOT 5 is silicon-based

Still don't explain what I see in the vid though. I would track down what fluid he used. If he used either Dot4 or 5.1 and your bike calls for Dot 5, you have issues. While technically, visually the two will not mix, as say in a jar even if you shake it, there is a microscopic reaction where the two can meet, say at any of the rubber components in the master or slave. This can expand the rubbers beyond imagine, jamming up the system. Slave not retracting as it should as one example. This could cause your clutch slipping. Unfortunately once this microscopic reaction has occurred at a rubber interface, there's no saving the expanded components, regardless of how many times it's flushed. Those components remain expanded from then on. They need to be replaced. 5.1 is a high performance Dot4 formula, that Ducati might use. I'd try and find out if he used this for you Dot 5 system. On a side note, Dot 5 other then easy on paint is the worst brake fluid shit ever devised by man. It has so much oxygen in it , it's actually compressible and this can be felt in the lever or peddles when comparing identical systems using one or the other fluid. Obviously if the system calls for it, use it for obvious reasons.

Looks like "Duck" poop......... not expecting the best from what was seen in video.
Agree, something weird going on with this fluid thing. Now a nice dirty brown or grey, that would make sense.Looks like "Duck" poop......... not expecting the best from what was seen in video.

Just rechecked my service manual for my 2006, and it states DOT4 fluid is used.............
Update
Went for a 2 hour test ride. Clutch isn't slipping anymore. I'm glad that the other day I didn't keep pushing it when I felt it slipping and drove back home slowly 🥵
Now when on 1st gear at a complete stop it will go into neutral easily 8/10 times. In 2 weeks I will check and replace/purge fluid all over again and see what results I get.
My early conclusion is that the Ducatista put new fluid in the reservoir after cleaning it, but left old fluid in the lines and slave. Hopefully he didn't put fkn DoT 4 or 5.1

When the clutch steels got some heat they can start warping and this will cause harder release or even dragging. Clutch thickness gets bigger due to warpage but there is still same release distance. And if cylinder movement is restricted by poor liquids it will be even worse. Typical symptom is that neutral is harder find especially from first gear side. And slippage too if mass plates are worn too.
Perhaps time to replace clutch if flushing the fluids will not do the trick.

this right here is KEY i know this from flushing fluid when racing the mustang at the track.
that being said, get a pressure bleeder, those things are amazing i'm sure someone makes a cover or you can buy a second cover for your reservoir and drill it and put a fitting on it. these things are incredible for flushing the system. you put pressurized fresh clean fluid through the system with no air at all in the lines. absolutely fantastic tool 100% must have for doing your own work. only like $60 USD when i bought mine a while back on amazon

Clutch is slipping again.. Last night I got home, got my camera and went out to replicate the issue so I could show you. At the start it might look like slipping by the rpms, it is the back wheel slipping on 1st and 2nd

Yup, clutch slipping for sure. As for the tire spin first and second, send me that PC cal and I'll detune it for you. 🤣 Seems to run decent.
