Something else you may want to do is test your oven for hot spots.
The way I do this is to go buy an inexpensive loaf of sliced bread, bring the oven up to temperature and then open it and quickly lay out slices of bread all across one of the racks, front to back and side to side, leaving about an inch between slices. Close the door and let the oven run until you can start to see obvious browning through the door. Then open the door and see which slices are more brown than others, that will map where your oven's hot spots are.
If you do this at multiple rack positions (my oven has just 3 positions) you may find that the hot spots aren't in the same place at different rack positions.
I have a Maverick oven thermometer that is designed to measure average oven temperatures, not food temperatures. It hangs below the shelf rather than being stuck in a roast. (I wish it had a setting to switch between average and in-the-moment temperature.)
I've also used a Polder digital meat thermometer which measures current temperature rather than average temperature.
Anyway, what your oven measures is the temperature at the sensor, not in the middle of the oven. There are a number of factors that can contribute to non-linear readings.
There are ovens that have more than one temperature sensor. I'm reminded of the old saying that a man who has a watch knows what time it is, but a man with two watches is never sure.
I find when I check my oven dial for accuracy, generally using two digital oven thermometers plus an infrared gun, that it if it is pretty much dead on accurate at 350, it'll be off at both 300 and 400, and not necessarily in the same direction.
How is it handling hysteresis?
Hysteresis, for those who don't remember the posts on it from the King Arthur Baking Circle, is the process by which thermostats cycle the heat on and off, so that the temperature averages out to the desired temperature.
An oven will go past the desired temperature, perhaps by as much as 25 degrees, because heating elements don't instantly stop producing heat when turned off, then the temperature will drift down back through the desired temperature until it gets enough below that temperature to trigger another heating cycle.
Placement of the sensor(s) is an important factor for the oven designer, as is the developments of thermal (air) currents under various types of oven loads. Any baker who has tried to bake 3 large fully loaded cookie sheets at the same time will have experienced the way the oven load diminishes air flow to certain areas (usually the middle sheet.)
Putting a heavy item (a thermal mass) in the oven, like oven tiles or something made of iron or steel, is a way of narrowing the peaks and valleys in the hysteresis cycle, but of course that lengthens the pre-heat time because that thermal mass has to absorb heat. And that thermal mass can also impact the air flow in the oven.
Convection oven fans are designed to increase air circulation, which generally means more constant heat and faster cooking times, because the oven is more efficient at heating the cooking utensils and the food in them. It also generally speeds up the hysteresis cycle time and, if properly designed, will narrow the range between the top and bottom temperatures seen at the sensor.
Ham has more carbs than do some other types of proteins, like beef or chicken. Sorry if that wasn't clear.
These days we seem to have to choose between a ham slice or a spiral sliced ham, both fully cooked. The spiral sliced ham is really too much for the two of us. Ham is higher in carbs than other proteins, probably due to sugar-curing, so we haven't had much ham lately.
Is your oven totally non-functional at this point, or could you use an oven thermometer to reheat a fully-cooked ham?
I'll make the pie dough tomorrow night and make the pie Wednesday evening, which is also when I'll check to make sure the turkey breast is fully thawed. Dinner's at 5 or later, so I don't have to start cooking at an ungodly hour. When I was a boy, my grandmother used to do two seatings for Thanksgiving dinner, one at 11AM for her relatives from Iowa and another one at 1:30 for the local family, including us, after my grandfather closed the drug store for the day. She'd start one turkey cooking on Wednesday and a second one at 5AM on Thursday. And these were 18-22 pound behemoths!
You'd think she could have narrowed it down a bit.

If I find hind quarters on sale, sometimes I'll brown them in the oven and make brown chicken stock, discarding the meat afterwards, but usually I use a whole chicken (without the giblets) plus any bones that I've saved up from when I debone breasts.
I wish I could find an expensive source for chicken backs, though. I"m not paying $1.99 a pound for them and the online sources all seem to be for pet food and are labeled not for human consumption. One of these days I'm going to contact the Smart Chicken folks in Tecumseh NE to see if they'll sell me a 40 pound box of chicken backs from their cut-up chicken production line. Tecumseh NE is only about a 30 minute drive from here.

I made another Celebration Challah, it came out about as nice as the one I posted a photo of a few weeks ago. We took it to a dinner party and brought maybe half of it back home, so I'm looking forward to a little French Toast.
The question still remains, what kind of baking powder are they using, does it use aluminum or not?
It may depend on when and where the chef/baker was trained. Some cooking and baking schools were late to the party on 'rediscovering' whole wheat breads. The artisan bread movement started in small bakeries and home kitchens.
I was interested in his $6000 flour mill, which looks like it is made of wood, I wonder if it was custom made?
Many sea salts are naturally high in iodine and other trace minerals. Himalayan sea salt is said to be especially high in iodine. (There's the makings of a joke there.)
Foods other than seafood that are said to be rich in iodine include:
Navy Beans
Bananas
Strawberries
Turkey
Milk and milk products, including yogurt and cheese
Prunes
Eggs
Green Beans
Corn
Potatoes (especially baked, other forms of cooking may leach the iodine out)However, fruits and vegetables may not be as high in iodine if not grown in iodine-rich soils.
Followup: This article seems to suggest that most processed foods do not use iodized salt.
Perhaps the most useful information in this article is the sentence that notes that if a food manufacturer uses iodized salt, it must list it as iodized salt on the list of ingredients.
I'm not sure whether prepared foods use iodized salt or not, either. I might have to make some inquiries.
I grew up in a small town in NW Illinois in the 50's and 60's, farmers with goiters were not unusual, especially among those who mostly ate 'off the farm' all year long.
