Tri-X in Tmax developer 1:7 Development times ?

[maddoc]

This question may have been answered already but I couldn`t find anything about developing Tri-X (rated @400 ISO) in Tmax developer at 1:7. Kodak`s datasheet only mentions 1:4 for Tri-X. Any experiences (development times at 20 degrees) ?

Thanks,

Addition: I tried and found that 9 minutes with slight agitation (first 30 seconds, one inversion per one minute) works fine.
