I am leaning onto about 50% to 60% loses with the numbers taken from this post here:

So at best 3 to 4 divisions still left after disengaging from Sala-128 with 1 more division left at Nezel as a reserve. In my head I planned to have Duskcrown still alive but both Soshrets that went to Sala-128 to have died, for some political drama and to have her promote Stillstorm to Soshret after some much needed explaining.
This is because the seven divisions that jumped to Sala-128 didn't immediately go there because of a dire need of replenishment and ship reshuffling due to casualties sustained, so they lost some extra time doing that, I would say about a day, day and a half. Until the arrival of these seven divisions the fighting at Sala-128 should have been somewhat balanced with about 7 to 8 Loroi divisions against 9 divisions which are led by the Stray. After the arrival of the reinforcement things would go to hell really fast but in my estimates the numbers should align. I planned to put Umiak loses in Sala-128 to 4 or 5 divisions.
P.S. I plan to have this offensive be the tip of the spear that wasn't detectable via farsense, the shaft that is detectable is on the way. And there have to be probing attacks underway throughout the Seren front, not the numbers arrayed against Tinza but enough to keep the main fleets busy.
