For phase 1 sign offs, I did loops, rolls, and spins. Loops were entered at 160kts and 2.5G pulls and rolls also 160kts and 15 degrees nose up prior to rolling. The goal is to show these maneuvers can be done safely at xyz speed which may or may not give you the best IAC score, merely that they can be done safely. Spins obviously at stalling speeds. Be sure to list each maneuver and entry speed used in your phase one sign off.
