Nice to see you back in better spirits than you were TD. I would say the machine is level enough.
The main thing with these machines is that all corners are on a firm footing so that thing doesn't rock in any direction.
It won't matter if it's not truly level as long as it is definitely not on a lean. If it is able to rock then when it goes into the spin cycle it can and probably will move.
Take care when doing that work as it is very easy to do ones self a mischief, good and proper.
