Exactly what Stephanie was teaching us. We started out the week (!) on Castor --> Chicken Blitz, did Spencer's Bowl --> Lower Inferno x2, Al's Run, Walkyries Glade, Tell Trees, Psycho Path, among others, and ended up with Lorelei. At the beginning of the week I was pretty petrified on the steep blacks, but by the time we did Walkyries Glade and Lorelei we were just gliding down the bumps!
Steph also stressed the importance of knowing when the conditions were right for doing certain runs, depending on the snow amount, whether the snow was deep/fresh/had been in the sun too long, or blown off by wind,etc.
She also gave us her definition of a black diamond vs double black diamond run: single blacks are difficult, but have "options", whereas double blacks can only be skied one way, and if you mess up, "you're toast", LOL.
