SFX Question...

How much, if any, focal compensation is needed when using SFX film?  Since it
isn't "true" infrared, I'm assuming it isn't that much...

Also, since SFX only extends to about 750 nm, does anyone know how long of an
exposure I'd need if I wanted to try it with a Wratten 89B or 88A?  Would it
even be worth it or is that trying to get too much from this film?  Would it
be best to stick with a filter with absorbtion limits at or below 680nm like
a #70, #29 or #25?
