In other words, a value appears of 175. It's gray and never confirms. A later transaction appears for 175.23 and never confirms. A later transaction appears for 175.87 but never confirms. Finally, a 176 appears and confirms. I am thinking, despite looking like separate entities, they are the same? Can someone confirm if that's how this wallet works?
It will be about the same value as you have the mining pool payout out at a set value, so the payment received in wallet are about the same every time (roughly) and the percentage for PoS is the same.
Can you post links to some screenies so we can see stuff (if you use dropbox ctrl + print screen auto uploads and puts link in clipboard).
