Any experience with D-19 developper?

[Cor Breukel <cor@xxxxxxxxxxxxxxxxxxxxxxxxxxx>]

Intregued by the statement of Michael Fulks in his interesting article
about IR on the WEB (http://www.apogeephoto.com/something, can't find the
rest )
"D-19 it is generally used as a graphic arts film.  That means it tends to
be high in contrast and grainy, but in my experimentation this has not
been the case. I get good contrast, easy to print negs, with subtle tones,
sharp grain and acutance"

I set out to try it: thusfar the results are bad :the first film which I
really blew. I started out with my standard setting (Minolta X300 on 250
ASA, +2.5 stops dark red filter, through the lens metering; gives good
results when processed in D76 1:1, 20 degC for 11 min), bracketing in
steps of 1/2 stops to +2 and -2 resulted in grossly overeposed neg's, even
in the -2 stops (1000 ASA in the camera) case.  Processing according to
Kodak : D-19, 6 min at 20 degC. 

So it looks like it that D-19 devell. is increasing film speed
considerably. The other half of the same film was exposed in the
combination Horizon 202/mystery filter (obtained via WJ;  it's nearly
opaque, probably +5 stops) gave the same results, infact I obtained just
one reasonable well exposed neg (didn't print yet, infact it's drying now,
so I can not say anything about grain etc.) but this neg was wrongly
exposed (infact 4 stops underexposed, metering with handheld Gossen on 50
ASA=> 800 ASA) 

Anybody  has experience with the combination HIE/D-19, or any commnets on
the above?
