Water boil test compares alcohol stoves of same design with different jet setups

Alcohol stove test compares boil times of same design stoves with different jet setups. Test uses Heineken pots for water vessels. It appears from the test that stoves with the jets closer to the top of the stove are more efficient at using their fuel. I don't have a good answer for that, just these tests showing my results.
