Question: How to tune up to standard tuning from lower tuning?

Here comes a “dumb” question that I have struggled with.

I have EBMM Majesty but I guess it is the same for every guitar with floating bridge.

When I tune down from standard tuning to D or C what I do is I put a piece of cardboard under the bridge to prevent the bridge from sinking and I tune in the nut. When the guitar is tuned I remove the cardboard piece, suddenly is the guitar out of tune and the bridge is not parallel to the body of the guitar anymore, I solve this by tuning again but this time by turning the screws on the backside of the guitar. By doing this the guitar is now tuned and the bridge is parallel to the body of the guitar, all good.

My problem now is to go to standard tuning again, I have tried to do it by just tuning in the nut but the bridge is too high and not even close to being parallel to the body of the guitar. What I think I’m missing is the control over the bridge, which I have when tuning down by just adding the cardboard piece under the bridge. When tuning up I would need something that prevents the bridge from rising too much. What can I do?

Thank you beforehand!
