Didn't you know that even when you don't leave your wallet open it gains staking weight, stake weight is what determines how quickly you can stake compared to the networks weight, the networks weight is everybody else's individual coins weight combined that you are up against, the more coins one has the better, the longer you wait means you won't be missing out on anything besides seeing it say "You minted a block with this fraction of a percentage" instead of it being in a lump sum, staking secures the network when you leave it on, staking is like mining, you are solving problems with your coins weight, you could have hardly any coins and get lottery lucky and stake a lot or you could have the same amount of coins and only stake a couple of times or not at all.

The more coins you own, the faster you will stake and more consistently depending on how many other people are trying to stake at the same time.

When someone stakes then the network weight goes down but in turn other weight might build and bring it up again, it's a cat and mouse game.

Don't trust those in wallet stake time estimations either, they are all wonky and incorrect.
