In my experience, TMax takes more than just a rinse or two to lose its dye. The emulsion has to swell and soften first, before the dye will be released completely, I think. The Film Developing Cookbook recommends 3 stand washes of 5 min each, i.e. fill with water, stand 5 min, discard water, repeat...

For other films, the dye is really not much of an issue, and I more often use 1:25 without a pre-soak. Anyway, it is good to experiment and see what works for oneself. TMax (both versions) is a great product, and worth the extra bit of effort.
