Cura 2.3.1 time prediction on UM2+ display

[LePaul 331]

For the record, the Cura time is pretty accurate

I'm just really curious why my printer display changes so much?

First the machine says 19 hours...

Then it goes to this?

...it eventually comes down. Maybe the raft in my print is throwing it off so much?

OctoPrint does the same thing. It just takes the amount time taken to process the gcode data so far and estimates the time left based on amount of data left to process.

Rafts print a lot slower and are mostly straight lines (very little gcode commands printing very slowly), so it thinks to process the rest of the print will be just as slow.

After the rafts are done, print speeds up and commands become more frequent and complex, so the printer chews through them faster and the time estimate drops.
