I just found some printouts from a site with developing data (also on 
my homepage, in addition to George Smyth's site):
HIE:
Rodinal (1+25) 9min
Rodinal (1+50) 12min

Konica:
Rodinal 1+50) 5min

It will still be an increase in IR-effect over 89B, but it is getting 
mighty slow. 
I will soon have to test it, as I have a 120 format Kowa fisheye that 
only accepts thin 'gelatines'. I can only use Konica, and the only 
thin polyester filters are #25 and #87....#25 won't give me the 
IR-effect I want, so #87 it will be!....8-))
I only hope that my EI is not much lower than 1 ASA, as the T-setting 
on the lens doesn't work (no B-setting present either). That leaves 
1s as the longest shutter time....with the sunny-sixteen rule I can 
get away with 1/2 or 1/4 ASA, but not much less....8-))
