90% of the time I can reproduce a Bb and work up from there to the note that I want.
Most time if I do not think about it I can correctly pitch the starting note of a piece I am familiar with. If I start to think about it I doubt myself and lose the abillity.
It is very rare for me to have to re-start a song because I have pitched it too far away from the correct note.

I do not claim to have perfect pitch because I am not perfect!
