Looking at the original XTOL data sheet for Tri-X 135 @ 400 diluted 1:1 you see 65 - 8.75 68 - 8.25 75 - 7 80 - 6 Your method of agitation will change these times. The Kodak method, which requires a darkroom and the addition of the film rolls directly into the already filled tank and then putting on the top, has a 5-7 inversion cycles in 5 seconds then 30 seconds still and 2-5 cyles of inversion every 30 seconds after that until the time is complete. Most of us, for dilute solutions of XTOL (1:3) allow much longer times especially toward the end of the development cycle. I think I'm safe in saying this. Times for 1:1 upwards of 13 minutes seem to imply water temperates of 50 degrees F which seems darn cold for tap water. Adam
