Never thought of that. 6'' of line on each perimeter loop would move the stake away from the tent fabric, allowing the stake to be pinned by a rock without it mashing into the space inside the tarp.
Besides, rocks sitting on the tarp fabric are easily bounced off under windy conditions.
BACK TO MY ORIGINAL POST, WHICH STARTED THIS THREAD: Many have commented on how tough the MSR Groundhogs are, and were surprised that I bent a couple. This makes me wonder whether I have Gen-U-Wine MSR stakes here. They are red-anodized aluminum, they have the three-pointed star cross-section, they have the notches near the head, they have holes in 'em for passing a bit of cord through; but they are 9'' in length and, unlike the photos I've seen of Groundhogs, did not come with a cord loop at the head.
Maybe what I've got here are counterfeit? Made out of whatever is the opposite of 7075 "aircraft" aluminum, but something wimpy and pathetic like 2024?
