Default Cruise timing?

I'm just curious how much timing some of you are using at cruise speeds of around 70. At 70mph running about 2100rpm and I'm commonly in the 38º-40º of timing range with my own truck. I was just curious how high others are running?

Here are a couple of logs from my own truck on the highway. I have many other logs from Radix, Procharger, high compression, strokers, etc. I was just curious about this because I've asked some about this and get odd answers. Some have said they run 30 degrees like it was a high number and some others have told me that they get away with 40+ like high 30's is nothing. I know that this is a very load dependent thing, but I'm just curious to see what others have run or do run. I commonly shoot for 36+ for example on an SS awd Silverado. I have logged many that were set up for mid to high 20's and I'm just curious if this is a common thing and maybe I'm just out there.
