In previous years Alissa did 3Lz+2T, 3F+2T, 3Lz and 3F -- using the +2T to allow her to do two Lutzes and two flips.
Her 3T+2T this year does not gain her any such advantage because the only jump she repeats is the Lutz.
Yeah but you have to consider that the Flip is her most inconsistent jump (aside from the Salchow, I guess, since she never even tries that jump). It's better for her to not attempt it twice.
