7 minutes, 40 seconds at 26°C/78.8°F
Continuous agitating for first minute, then 5 seconds every minute.
Fuji Super Prodol is the cheapest developer in Japan. I got the idea from a member on APUG.org (also here http://www.e6eye.com). He pointed me to Junku Nishimura's recipe and told me to adjust -10% of time for the old lens Junku's using.
These are the results.
Let me know what you think.
