When doing a test of any kind you want to limit your variables to if
possible only one thing you are looking to test so the end result shows what
are you are looking for not numerous other things.
Tina  when your put your camera on a tripod to test your film or lens you're
not testing your tripod. You're testing the sharpness of your film and or
lens. Your just taking out the variable of the hand holding which is quite
high.
If you don't use a tripod it could be said all your testing is your hand
holding ability.
Exceptions would be be if you were using a flash whose very fast durations
make for a realistic expectation of how much sharper one lens might be over
another. Or film or sensor.
Perhaps another would be the Bonneville Salt Flats at high noon.
On a Tuesday.
