[OM] how to determine light loss from diffuser

i've made a diffuser using part of a rubbing alcohol bottle, such that it
snapfits into that dovetail thingy on the T32 head/lens. now, i dont have
a flash meter, but i'm guessing i will lose about 2 stops. is there a way to
check exactly how much light is lost by putting similar larger sized piece
in front of a lens and checking the meter? or is that not going to
work? thanks,
