what should the compression be in the cylinders? I don't want the ratio. I want the compression reading when you do the cyclinder compression test. I got about 200psi across all the cyclinders. which is good that they are all the same. I got this number by turning the engine over three times, and then repeating three times on each cyclinder.

Bentley says 128 psi minimum with 28 psi max difference between cylinders.

 

The actual figure is unimportant, especially being as an inexpensive tester can be way off. 200 seems high but there's no way that's not just the tester.
