Is a dished piston at "Zero Deck" still zero deck?

[MrSony]

Say I have a piston with a circular 14.75" dish, but the "ridge" around it, is at zero deck, aka flush with the deck surface. Is this still considered zero deck?

For clarification, the compression calculator I have spit out my nonsense as this:

Just playing around with the numbers, but my point remains the same. Might be my lack of sleep, or my anticipation for whats to come later today (3:34AM here), but I can't seem to come to a conclusion myself. Any input is appreciated.

I'm not seeing a problem.
Yes, I would say it is zero deck; anything above is considered "out of the hole".

Yes it's zero deck, you just need to include the dish volume which you did so you're good to go.

piston deck height is measured to the flat part of the piston. Dome or dish volume has no bearing on deck height.

What's your dynamic compression? That's more important than static.
