    Adjust the exposure settings to provide for “normal” exposure, and then
    increase the aperture number or shutter speed setting by four full stops.

    Increase? Example.. Metering at 125 at F8 for optimal. It says increase four full stops? Are we talking 125 at f32 or the other direction?

    I also read that people are using a simple styrene cup to flash.

    For preflashing you want to hit the film with very little light.

    125 at f32

    The advantage of pre-exposure (pre-flash) over control thru development is the highlight and midtone values are minimally changed while the lower values/shadows have reduced contrast. As Ralph Lambrecht says, this enables easier printing on graded papers. His example of how to use is once you have an overall meter setting for a scene (a Zone V), then reduce by 4 stops and expose for a zone I thru the disc. Then expose normally.
