I use the tables that I got from an article by Howard Bond in PhotoTechniques magazine. They are highly accurate and he did testing for older Tri-x and Tmax films and then redid the tests for the newer Tri-x and Tmax and HP5. The earlier tests actually include the movement of zones for the appropriate times. . I use them for APX100 and PL100 also;just interpolate. If anyone cares to have a copy just send me a PM with your address and I'll be glad to share.
Best, Peter Schrager
