Testing the light output of a strobe.

Hello,

Am looking to test an AD600.

According to the specs it has a guide number of 87 at ISO with a standard reflector.

I used a 7 inch reflector and tested the strobe with a light meter at 100ms, ISO 100 and am getting  consistent readings of f51.

Is this the right way to do it?

Should it be 87 at 1 m?

Thanks
