And you're all neglecting the fact that the original question asked for
UNDILUTED times.  I, like most of the rest of you are using D76 for
11 minutes... but note that's at a 1:1 dilution.... and I'd be willing to
bet that most of you that develop for 11 minutes are at 1:1 as
well.  No dilution would be a far shorter time.... 8.5 minutes
sounds somewhat short. 

On another note, are people having any success with HIE in XTOL or ABC
Pyro?  How about other developers??
