Opinion on a compression test?

[JZano]

I found a fairly nice and clean coupe with about 170k miles on the motor. Did a compression test, but I might have done it wrong, or so I am thinking.

I was taught to kill the spark, pull one plug, test, put plug back in, move to next one.

With that I got between 135-145... But what i'm reading is 190 is best but shouldn't be lower then 150.

Car still ran strong though...

Thoughts?

Was it done after the car was at operating temp, or cold? That could make a difference.

Car was warm, I got a lot more info over here:
