Hello, I just wanted to clarify some rules— the liftee has to be touching the lifter, and not be touching the perimeter. It has to be at least 12 inches above the ground. Is this correct?
yes that is correct
And even though the rule says you can’t touch the perimeter, you can’t be supported by it at all (in case you were thinking of that…).
I do believe the rules say you can touch the perimeter 
(it was either a typo or I could be wrong xD)
the thing is, the rules don’t forbid you from touching the field perimeter, but because a high lift requires you to be entirely above the perimeter, you logically cannot be touching it
I am pretty sure the rules state that any lift, high or low, can be touching the perimeter so long as the ref can push the stacked robots away from the perimeter and they will remain stacked (so the robot is not supported by the perimeter).
The definition of elevation was updated. For High Elevation you can’t be touching the field perimeter at all, for Low Elevation you can but it can’t support you.
Yes, I meant you can touch the perimeter, but you cannot be at all supported by it in a lift. In your original post Kevin you said that you can’t touch the field perimeter. You can touch the field perimeter (if i’m correct), but you cannot be supported by it. So for instance you could theoretically be touching the wall to align yourself as long as at the end of you lift you are completely free from the field perimeter. At least, to the best of my understanding.
For the sake of preventing any further misunderstanding, the definitions I posted above say that a high elevation cannot be touching the field perimeter at all, and a low elevation can touch the perimeter but the robot cannot be supported by the wall. Of course you can still touch the perimeter as much as you like throughout the match (and potentially while lifting), you just have to meet the above criteria at the end at the match for the elavation to count.
