Speedlite Light Modifiers Comparaison

Bonjour Everyone,
I had quite some trial and error on location regarding the output of light that some of my modifiers would have.
I wanted to find out the potential output and light loss for my most-used modifiers and share the results.
The speedlites that I use are Canon 600EX-RT.
I know that the quality of light would be better evaluated on actual people faces rather than on a lightmeter but I wanted to know the max light output I would have for each setting.
You can find a summary of my findings in the table below as well as all the associated pictures in the gallery http://www.loriskim.co​m/light-modifiers-comparaison.
