The 5,6,7 coats is Simple anytime your pulling a set of 33s off the rack , older harder heat cycled more, and doing all prep track side is that's what it takes or the tire would simply run out of prep , So the xtra coats are what's required to get prep into that set of tires surface .You've nailed me here. It does drive me nuts because it does t make sense. I get some oil making it grip better. But, I don't get 5,6,7 coats.
After your post earlier I decided to ask the track how they prepare the track. They only have one race per month and it usually is a pretty good 150+ kart count event.

"Sure I don’t mind. We don’t ever till it. We only tear it up if it gets rutted out due to heavy rainfall in-between races or if we change the track surface in anyway. Then we don’t necessarily tear it up. I use my Harley Power Box Rake attachment to work it up,fill in the ruts,level it and condition the dirt. Then we put a 1000gal of water on it let it soak in for about 30/45 minutes then we roll it in with the track trucks. Then if it needs it we drag the fluid filled turf tread tractor tires over it to fill in the smaller spots until they’re gone. Then we water it again and drag the tires over it till it gets smooth and shiny on top. We have never used calcium we don’t like it."
Here is a picture of the track.
Based on those pictures of the track , If they took a different approach with there track prep , instead of ALWAYS slicked over lots of prep, it would be NO prep Never prepped for 33s ALWAYS .
