Neck Relief on a Mandola

[Ray(T)]

My mandolins generally have dead straight necks whilst my GBOM has around the same as my guitars but how much would people allow on a Collings Mandola?

I've got between 0.15 and 0.2 (the only feelers I have in range!) on my Octave Mandola - Ashbury E-style with a 518mm scale.

I put a capo at the first fret, fretted at the 12th and measured at the 8th but can do other variations if it would help?

I would say "just enough", I tend to go as straight as I can get and still play clean - which is to say trial and error - it shouldn't need much for sure.
