Wanted to see a certain part in the manga and got sucked in for hours without even noticing. Re-read the Nappa and Vegeta fight, the whole Freeza fight, the whole Trunks arc and first half of the Android arc, and some bits and pieces of the Cell Game and Boo arc in the last two nights
That one fusee having to lower their battle power to do the fusion dance doesn’t necessarily mean their full power isn’t factored into the resulting fusion.
Gohan would have to match his power to Goku's to fuse because you need to be perfectly in synch to perform Fusion. There's no statement or implication that this would impact the resulting fusion's power.

Regardless the statements about a hypothetical Gogeta's manga strength are fairly vague and taking them to mean SS Gogeta specifically is a fine interpretation but not really supported by anything. I'm not sure what the metamoran Gokhan...
There is no reason. My assessment is entirely arbitrary. There's not enough information available to accurately gauge Gogeta's strength compared to the fighters on the gauntlet.
