Dave I bought my 87 930 4 years ago in the low 40ís on mileage. Leak down was 3% across all 6.

I have 46k on the clock now and the dam thing pulls like an OX! No smoke on startup ice cold.
Like Bryan said anything south of 10% is just fine IF the car appears loved.

Funny you mention #6, I owned a new Boxster that bleed like a biotch through that cylinder, but only sometimes.
Mech told me that it depended on where the piston/valves were positioned when you shut the motor down :/

Good luck!
