Don - I think the time Konica give for D-76 means straight (undiluted)
D-76 developer.

I have used other developers too, like Ilford Ilfotec LC29, Kodak TMAX 
and Agfa Rodinal, which is my favourite developer for Konica IR.

I usually shoot Konica IR at EI100 metered through the lens with
red filter (#25 or #29) using my cameras built-in meter.
My developing times at 20C are:
        Ilford Ilfotec LC29 (1+19)  5 min.
        Kodak TMAX          (1+4)   5 min.
        Agfa Rodinal        (1+25)  5 min.
        Agfa Rodinal        (1+50)  8 min.

Look at the pictures (Georges, mine and others) in the Infrared Gallery!
