If you have a proportional thermostat, it automatically compensates for changes in temp. I noticed that in my 72F room, the element runs in the high 50% range to maintain a constant temp. If I remove the lid and allow cool air inside the unit, the element will crank up as high as 100% to reheat the air, and gradually wind down as it approaches the target temp. I really like this feature compared to on/off thermostats. I'm certainly not an expert on incubators, but I can only imagine that constant cycling on and off leaves a lot of room for temp fluctuations. All the research I've done on thermostats seem to point out the advantage of using proportional thermostats over bi-metal thermostats. If any adjustments need to be made, it's as easy as pressing a couple of buttons. No turning screws and hoping for the best. Just wanted to throw that in... lol!
I discussed temp differences in my incubator with the folks at Incubator Warehouse. They told me it's normal for it to be warmer in the corners because air doesn't circulate as well in those areas. Since most turner motors are located in a corner, that could account for the higher temp. The only way to confirm it is by checking all the corners.My incubator runs about 2 degrees higher in each corner even without the turner running, so if I fill the incubator, I'm afraid I'll have to "meddle" a little more than I prefer due to shifting eggs around so none get cooked.
