I use a surgical tape called Micropore. It's papery, thin and peels off
easily, like masking tape. It diffuses the flash just enough without
robbing loads of power, and costs next to nothing.

It would, but only up to the limit of output. You can use manual and normal
auto flash as fill-in by setting an aperture one smaller than on the flash
(e.g. set lens at f8 when flash panel says f5.6). The unit then gives the
light required, but only 50 0ets to the film - results it 1 stop under
correct illumination.

Either trial and error (using slide film to accurately show the exposure
variation) or a flash meter, as you proposed. I use the tape mentioned
above, because I can cut it to fit the flash window, and thereby retain
normal auto, which uses a cell in the 'O' of Olympus on the front of the
flash unit. I'd recommend using the minimum amount of material required to
provide adequate diffusion.
