It's actually not bad if you choose a freq where the reactance is 
less than about 100 Ohms. So for your 9uH use the lowest freq 
(1.8MHz) where the reactance will be around 100 Ohms. Use very short 
low inductance leads of course.

On the other hand the calculated inductance should be perfect, so why 
measure it?
