To do a proper compression test you need rotary compression testing equipment, not just Joe Garage's universal kit. You may have known that already, in which case ignore this...

You can get a decent test from a normal compression tester.. Just pull out the one way valve..
And you should see from ~75-120Psi on each rotor.. But more importantly, you should see 3 almost equal bounces and it should be close on both rotors..

I got that atkins rotary rebuild video and they demonstrate some compression tests. They used one of those universal adapters and gave a tolerance range. I forget what it was, tho. I've heard the compression testers that Mazda uses are very thorough and REAL high end expensive type stuff. Maybe she'd let you drive it to a dealership if you dont want to mess with a universal.
What you may also want to do is a coolant system compression test. I'd rent/borrow one of the testers tho, as they are a bit on the expensive side.
