need help can seem to figure out why wallet 1.9.1 says minting 1 days then reopen wallet next day 22 hours and then today it says back to 1 days

?
The estimate is based on how long you'll have to leave the wallet open. This is how it gains weight. So, if you have a 22 hr estimate, then close your wallet, you're going to be looking at another 22 hrs when you open it again. Sorry

Remember, the network is secured by the minting process. Mint is nice, because you don't always have to open your wallet, but when you do you have to do your fair share to secure the network. Hope this helps you understand.
