What is the deal with this thing?

Compression should be around 114 PSI.

Below 110 I'd keep an eye on it (yearly compression check, or every 1000 miles or so), below 100 you need new rings. If it's below 100 and hard to start you definately need new rings. If you wait to replace the rings, you'll eventually score the cylinder.

Above 120 and you probably have carbon buildup. Remove the head and clean. If it's still high, someone probably milled down the head to increase compression.

There is no "red line" to high compression; it is an indication of carbon buildup. Nor is it even possible with head/jug machining to increase compression beyond 140 PSI or so using the stock head/piston. 140# is still low enough to use regular.

Remember to crank the throttle open when testing.
