cant it be ' I am almost clear'
Is clear=ready a remnant from WWII? "Clear" is pilotspeak (plus some other scenarios like radio and detonation?) for "ready for [some maneuver, e.g. start engine/takeoff/landing]", or from the control tower, "you are cleared for [said action]."
That's what she said
"I am almost clear" should also be accepted, shouldn't it?
