Here are some drafts from my personal guides where I use the newly added Younger Gemini. You can use these as a comparison to see how much you would save or lose on those camps on your own guides. I skilled mine with 1-up and not with lightning slash since fast recovery was more beneficial in the adventures I play the most.
Tomb Raiders - No losses
The Buccaneer Roundup - No losses
The Island Of The Pirates - No losses
Witch Of The Swamp ~30R losses
Split City in Summer, Player A
Split City in Summer, Player B
Red Riding Hood
Snow White
Unknown Regions
Mountain Labyrinth
I will add more later. Note: Save the images if you like to use them later as they might disappear from imgur at any point.
