Alright, I did a quick check.
Torval currently has 40 systems, 3,084 CC income, 1,608 CC upkeep and 1,313 CC overheads.
Let's check what could happen if HR 8104 was successfully expanded. I see no obvious overlaps in HR 8104's control sphere, so it should have its full radius income of 104 CC and its upkeep of 26 CC.
Torval would end up with 41 systems, 3,188 CC income, 1,634 CC upkeep and 1,415 CC overheads. This is a total surplus of 139 CC.
"
But Torval lost systems! She can't expand when she's lost systems!"
Well, this was FDev's response when Syntheng didn't revolt:
due to a bug, Miss Duval incorrectly remains running a deficit. Her expansions for the last cycle should have pulled her out of deficit, but this was sabotaged by a system in turmoil incorrectly remaining on the books rather than revolting, and dragging her income down into the red with its costs.
The result has managed to be both beneficial and baneful - she did not lose the system in turmoil (Syntheng) that she should have, but she did remain in deficit because of it.
In other words, FDev has stated that it is entirely possible to have a system revolt (Syntheng) AND get expansions.
As such, there is no economic argument that HR 8104 shouldn't belong to Torval. That means that either HR 8104 bugged out (and it's not like powerplay is littered with game breaking bugs) OR Torval lost her expansion fight.
Now, for some really intricate and exceedingly brilliant reasoning (yes, that was sarcasm), there is no "paper trail" for each cycle. We cannot reliably see the actual numbers put into each system. Whenever we check the powerplay section, we're
always seeing some cached data that has no age attached to it (so it could be 15 seconds old, it could be 10 hours old - you have no way of knowing). And once the cycle is over, the data is reset, so you don't get to check by how much/little you lost each race you found yourself in.
You might be subject to last minute sniping that put you into turmoil, but you don't get a chance to see by how much - just that it happened. And it's even worse for turmoil systems at the moment, because you don't get to see which ones of them were actually accounted for as fortified/undermined, nor by how much once you've lost them. You just have to blindly trust the system.
The system may be flawless, but while I can't speak for anyone else, I want to see the numbers! Not just for HR 8104, but for all the systems. It's flat out moronic that a game element that is as reliant on strategy and organization as powerplay is so completely dependent on manual data entry.
