except a portion of the check ride was done in a multi for the one engine out NPA..
There you have it, the PTS says to perform a non precision single engine.
Thats all that is tagged on to your multi check ride if you are instrument rated.
Makes sense in a way. Most people I know didn't get their initial instrument in a multi, looking at $125+ CFI an hour for some good shape 172 versus $250+ CFI for some beat up Apache, even when doing it in minimum time you need some 30 hours in the plane. But if you absolutely need the multi time, this is the way to go.
