Does turning a gas stove on high move the heat to the outside of the pot?
When you turn a gas stove on high, you get a big flame with a wide diameter. When you lower the heat, the diameter of the flame shrinks. (I'm not sure this description makes sense. Does it?)
Does turning the heat up all the way move the hottest part of the burner to the outside of the pot? And further, does reducing the heat just enough to shrink the diameter of the flame cause the heat to be more evenly distributed across the bottom of the pan? I've noticed that, while trying to boil water, it tends to boil first around the edges of the pot and doesn't necessarily ever get to a big rolling boil like I've seen on an electric stove.

Is your pot too small for the eye you are using? If the pot and the flame diameter are roughly the same size the effect you're describing probably happens.

Quick Answer about "Does turning a gas stove on high move the heat to the outside of the pot?"
Given that design, I would imagine that yes, if you turn your gas up too much the flame will tend to heat up the outside of the pot.How does gas stove transfer heat?
Convection refers to heat transfer in fluids and conduction in solids. For a natural gas stove, convection heats the bottom pan of a skillet, allowing for conduction between the skillet and the food. Quality thermal conduction relies on molecules in a solid moving together in synchronized motion.Is cooking on high flame good?
Cooking at high temperatures or on high flame robs the nutrients out of the food and can also be harmful to your health in many ways, says Dr Bhavi. 2. Ensure food is cooked thoroughly: More than the temperature, you should be careful about the rawness in your food.How can I make my gas burner hotter?
Gas ovens don't heat as evenly While gas ovens preheat faster than electric ovens, we found that they tend to cook more unevenly. Most gas ovens have a central flame location while electric ovens' elements are spread out through the bottom of the oven.Using the Gas Stove in the Kitchen

Answer 2
Your stove should have various sized 'rings', and as Philip pointed out depending on which one you use the flame on the outside of the pot effect will differ.
For my stove, the largest ring actually has two rings - so even if I turn the gas up, the inner ring will stay in the middle (the outer ring does tend to grow and sometimes go outside of the pot).
Given that design, I would imagine that yes, if you turn your gas up too much the flame will tend to heat up the outside of the pot.
On a side note, I believe that it is bad for the flames to be heating up the sides (especially the walls of the pot) so I guess it is best to use a pot that is larger than the ring itself, or turn the flame down so it is less than the diamater of the pot base.
Answer 3
Here's a trick. Take a few staples, and place them between the burner base and the cap. That will lift that metal cap off the base just enough to reduce pressure and allow the flame to rise from the center. It likely won't impact combustion as the gas and O2 have mixed prior to the point in combustion. This will "Loosen" the flame a bit and bring it back to the center of the pan. It works great.
