dasa compression ?

I have the same setup but with 8mm crank and get same compression as you, so I would say that is right.

Opening throttle to WOT whilst cracking makes a massive difference on the result - try it and you'll see.

I thought Nuclear reply was very clear and helpful, don't know why the 'butthurt '?

You should have the spark plug in on the other hole also when you do the check.
