As far as the apps, I am wondering if it's TeslaFI as STATS only pings the car when I open it, but I could be wrong.
As I said, I doubt the apps are causing much of an issue. Your problem is Sentry Mode. I would expect 4-5 miles a day drain at a maximum, with both apps running. It may not even be any different if you disable both of them. I've tried disabling Stats before and it made no difference to my drain, which is always around 3.5 miles a day (I only look for long periods of time). There are some apps that are poorly implemented which increase drain, I gather, but haven't heard bad things about either of these.
For vampire drain measurements, it really only makes sense to do them for very long periods of the car sitting unused. For example, I lost 28.91 miles in 208.6 hours. This is a very typical number and no one does significantly better than this, and there is currently no way to reduce it. For shorter periods, you can easily be thrown off by pack temperature changes, a period of time when you kept the door open, etc.
I have found that "typical" phone proximity, etc., makes nearly no difference unless you spend your day wandering around and around your car in the garage, or you park your car in your living room. The reason these things
could matter is that they can transition the car from sleep (where drain might be 5-7W) to idle, where drain is 200W or so (because it heats the windshield cameras, turns on the proximity sensors, turns on the cameras, turns on the DC/DC which uses the HV battery to charge the 12V, and probably turns on the computer as well). You can determine these transitions because you will hear the contactors "double clunking" closed. (It's a slightly different, quieter sound when they open.)
