Ahh, I forgot you didn't have a schematic for the 4400. I guess I am confusing the 440 and the 4400 since you have been going back and forth between them.
There still must be some large value cap in the indicator circuit somewhere though, otherwise lowering the shunt resistor would not make such a difference in the response time. It will be interesting to check when you find a schematic.
