Eric, as was said, you are correct on the grouser bars themselves having a good psi for compaction, yet the thin profile and wide spacing along with a short height, it would take probably 30 times the passes and in about 1-3" lifts to achieve equal compaction of one pass of a sheepsfoot and in 6" lifts. Compaction CAN be done with a track, but with excessive time and cost by comparison. That is probably why, for compaction purposes, grousers are not considered in tracked equipment, plus, they are designed for traction with minimal compaction. Wear down the grousers and you are on a slip-n-slide in moist clay. MU is correct in the 10-13 psi average, so is the psi for a spiked high heel (about 1/4" square inch heel surface on a 150# woman is 600 psi). That 2007 F250 will compact better with roughly 80 square inches at 75psi per.
If you look at the actual physics between a sheepsfoot and track, a track can never compact as well as a sheepsfoot. Vibratory sheepsfoot rollers are even better. By design, tracks provide minimal compaction.
Max, you should check the library on the home page here and consider buying Mike Otto's book, "Just Add Water". It will answer all your building questions!
