22 gauge is 15 ohms 1000 feet and 20 gauge is 9 5 ohms 1000 feet.
But in many cases it can also be caused by the wires that lead up to or connect between led strip segments.
For example the diameter of a 16 gauge wire is physically larger than that of an 18 gauge wire.
Since the leds are so efficient it takes a significant drop of voltage to visibly effect the light output.

As the voltage supplied drops the amount of current going through the led will drop as well.
In dc circuits voltage gradually drops as it travels along through a length of wire or an led strip light.
Most of the electricity an led light consumes is converted into light unlike regular light bulbs where a lot of energy is lost as heat.
Led strip light voltage drop.
When powering led strips voltage drop is commonly explained by insufficient copper quality or thickness in an led strip s pcb substrate.
