But be careful - you are already pretty low at 200C. I strongly recommend you do a simple test like the one I did in the above post as all PLAs are not the same both manufacturer and color. I'm told it helps to have a good quality PLA.
If you lower the temperature more you might get underextrusion which would mean you would have to lower the speed also although 50mm/sec would be plenty slow enough for me at 190C (100mm/sec would be a bit too fast for my grape colored PLA). This is also addressed at the above link.
Also you might want to add a clip: There's a blue clip on the print head where the bowden tube connects. You might want to make a similar one on the feeder. Other people seem to think this helps reduce how much you have to retract. I have one and 4.5mm is plenty for me.
Also 40mm/sec might be too fast for the retraction speed with the latest Marlin. I'm not sure - there's been discussion about this lately but I don't have the latest marlin so I haven't touched that setting.
But really I suspect the only thing you need to do is lower temp by 10C but don't waste another hour on this - do a test print first.
Oh - and to get better adhesion to the blue tape, wash it once with Isopropyl alcohol (aka rubbing alcohol) - found at any drugstore that sells aspirin and bandages. If you do that you shouldn't need to sink the bottle by 3mm.

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

You have "stringing". The simplest thing to do to reduce stringing is to lower temperature:
