[pure-silver] Re: Developing Plus-X in Rodinal 1+100

I've used a huge amount of PX over the past many decades. I still have fifty or so rolls of 220 PX in my freezer. Never at ASA 125. ASA 80 on normal or slightly hazy days, ASA 64 on bright sunny days. Incident meter.
14-16 min in D76 1:1, agitate every minute, 18-20 min in Rodinal 1:100, invert/rotate tank twice every TWO minutes. 70 deg F. 

It always seems to work for me.

Hi,
I'm planning on shooting some 120 Plus-X at the rated 125 iso and I want to develop it in Rodinal 1+100. I checked the Massive development Chart and it gives 6 min for Rod 1+25 and 13 min for Rod 1+50. What would be the extrapolation for the time if I developed in Rod 1+100? I figure a ballpark time of around 18-19 minutes. Does somebody have a more precise time?
In passing, is 125 iso a good starting point or should I be shooting with a lower iso, say 64. Haven't used Plus-X since high school in the 60's, so I am unfamiliar with what I assume is an updated version of Plus-X or has it stayed essentially the same emulsion? 

Any info about Plus-X would be appreciated, pros and cons.

Cheers,
Bogdan
