DPF Filter Regen's Way To Much--Help!

DPF Filter Regen's Way To Much--Help!
I have a 2016 Platinum edition 6.7L. I have a Edge CTS2 that allows me to see my DPF stats and lets me see when % full for the filter. Since I have owned this truck (about a year and a half now) the filter fills up extremely quick and I ma regening at least once a week. For example, regened on Friday (10 Aug) drove the truck a few times over the weekend for short trips to store and now Monday (13 Aug) I need to regen already. Under normal driving conditions I know it should auto regen about every 500 miles. Right now I akm showing an average regen distance of 142 miles and after todays regen I expect it to go below 100.
I have had this to the dealer countless times to no avail. They found the DPF nozzle partially clogged and cleaned it out. Re-flashed the ECU and about 2 months ago replaced the DPF filter itself. They have no idea what is causing it and since it is not throwing a code they say Fords official position is "there is nothing wrong". Despite this position the tech knows it is working correctly but cannot figure out why. I only run Exxon or Chevron diesel fuel, all servicing is done regularly (I know not related) and DEF is serviced by dealership.
Is there anyone else out there who:
1) Is experiencing the same or similar problem
2) Was able to correct this problem on their own or through the dealership
Any help is greatly appreciated. Driving this damn truck on the highway long enough to go through the regen every week (or less) is becoming a major pain in the a$@!

Do you have the Exhaust Filter screen turned on in your IPC (Instrument Panel Cluster)? If so, how low does it show the filter percentage?
You might not like the Dealer nor Ford's reply about it being normal but according to your Diesel Supplemental Owner's Manual, it is normal. See page 31.
The regeneration process operates more efficiently when you safely operate your vehicle at least 30 mph (48 km/h) with a steady pedal for approximately 20 minutes to complete the process. The frequency and duration of regeneration will fluctuate by how you drive your vehicle, outside air temperature, and altitude. For most driving, regeneration frequency will vary from 100 - 500 miles (161 - 805 km) between occurrences and each occurrence will last from 9 - 35 minutes. You can usually reduce the duration of regeneration if you maintain a constant speed above 30 mph (48 km/h).

Interesting to know. For five years 2.55 gpl was 90% and my truck would regen around 2.65 gpl. I think my record was 2.74% or so. In 2015, a firmware update on I'll assume the ECM made 2.55 100%. This was after my primary water pump was replaced because I remember the ECT cooled differently and active regens were 0.10 gpl earlier.

Ford has the max mileage between regens set at 500 miles since the last regen completed. Not so sure you get those miles between regens unless you are tuned or something.

I mainly drive the truck in stop and go traffic during the week for very short durations and towing on the weekends. I have never even come close to 600 miles between regens (Senix Comment) since I've owned this truck. The diesel manual may categorize this as normal as well as the Ford; however, the master tech at the dealership says it is not. Unfortunatley, he can't find a smoking gun. My hope here is to find out based on my driving cionditions if the general consensus is this is a typical interval for DPF regen or does it seem excessive. Should I see a more frequent regens during short commutes? I had assumed I would see more regens when towing.

I do not have the Exhaust Filter Screen turned on in the IPC...how do you do that? This is the first time I've heard that. Using the CTS2, I can see most of the DPF stats and do a manual regen.

You can get the dealer to turn it on using this thread that I posted photos on how I used the Ford IDA to enable the screen

Or you can use FORScan and an OBDII adapter and do it with a laptop.

Mine appears to be unique in length of regens, around 6 miles until completion too. My DPF always goes to zero upon completion too.
I am aware of the mandatory backstop of 500 miles, been that way since the 6.4, 2008 first generation of DPF's.

What I see is less towing more regens. More towing, more DEF useage and less regens.

I use PM22A and do get to the 500 miles on my '13. Clearly there is something else going on here. It would be interesting to see what % full the DPF is when it starts your regens. I believe you can turn that DPF % full screen on with Forscan if your dealer won't do it for you. The other confusing thing with this is "what triggers the regen pre 500 miles". Is it the DPF % full? Is there an exhaust pressure sensor after the DPF (GM has these)? Is it triggered by something else?
