I pulled up the dpf screen on the dash and it started off at 58% two days ago and it's up to 72% today.
at what point does it go into regeneration?

My 2017 NCV3 typically goes into regen after hitting 103% as shown on my ScanGauge II (the 2017 van didn't have a built-in DPF% display). The DPF% numbers do not appear to correlate linearly with driving distance or even conditions; mine will climb pretty quickly after a regen up to about 70%, then fluctuate up and down depending on power loading. Heavy power usage like climbing hills can make it run backwards, sometimes a little (couple of percent), sometimes a lot (10 percent or more). Eventually it creeps up and when it gets to 103% regeneration happens.I pulled up the dpf screen on the dash and it started off at 58% two days ago and it's up to 72% today.

Yes, normalI get something like 500-600 miles between regens. Does that seem right?
How's performance? What are these values? From instrument cluster?UPDATED WITH BETTER INFORMATION:
I'm on a trip now still determining normal. 100% = regen time. 14 minutes to complete = 0%. It seems like 0 to 60 goes pretty fast; then it decreases to 48%. 2% increase = 10 miles from (second) 48 to 100%. This is all highway at 60 to 75 mph.
The quick up to 60% and drop back to 48% was missed before. Does it everytime now that I noticed it. My original observation that 50 to 60% was slow, probably because I didn't see the drop to 48 and back up before.
Performance fine, but just running down highway at 75; 18.8 mpg (under 10 mph crosswind) (17.3 with 20 mph headwind 4 days earlier). Data is from vehicle DPF monitor "% vehicle load" as I recall is the term.How's performance? What are these values? From instrument cluster?
