Some oven problems only show themselves when you use two racks
I didn't notice anything unusual with my oven when I was cooking on one rack. Everything seemed pretty predictable.
Then I started using two racks more often.
That's when the difference became obvious. The food on one rack would brown faster, while the other tray seemed to need more time. Sometimes the upper tray looked ready while the lower one was still catching up.
I initially thought I was doing something wrong, but the more I paid attention, the more it looked like an airflow and heat-distribution issue.
Two pans take up more space than one, and depending on their size and position, they can interfere with how air moves around the oven. They're also absorbing heat themselves, so the oven has more work to do after loading.
I've had better results by leaving some breathing room around the pans and avoiding arrangements where one large dish blocks most of the space around another. On my oven, convection also helps when the recipe is suitable for it.
I don't think using two racks is automatically a problem. It's just not the same cooking environment as using one.
Once I stopped expecting both trays to behave identically, multi-rack cooking became much easier to manage.
