Yes, that is how a tracking test works. There's many different ways of doing it, but yes, it's done by shooting and moving the scope and then moving it back to it's original settings, and seeing if you're still hitting int he same exact spot. If you are, then you're good to go.
Reading online is rough for folks just getting into guns or serious shooting. Lots of bad information out there that will make you 2nd guess your choices. Always do thorough research. Also, not all forums are equal...Some seem to be filled with more bullsh!t and unmitigated bias than others. Most folks here openly admit our biases, in order to give the most honest and helpful opinions to others.
