    For that TMAX bottle i just simple dilute it from the concentrate or stock solution, i don't dilute the entire bottle, i just dilute part of it with water for 1:4 ratio, never had an issue with films i used with that dev diluted.

    What the op says makes sense, re the twice diluting.
    About the longevity question on the gallon (itself a 1:4 dilution) - I don't know if anyone has done this before, maybe PE can help with this.

    Developers mixed to working dilution tend to die after a day or two due to the oxygen dissolved in the water that you dilute them with. How dead it is will depend a lot on the details of your water (oxygenation, pH, presence of iron and/or other oxidising agents) and the developer (again, I don't know about Tmax). For example, D76 mixed 1+1 I wouldn't be much worried about at all, but Rodinal at 1+100 I would discard after a few hours at most.

    If we borrow from RA-4 chemicals (idea) to use Distilled water to mix and then fill up the empty portion of the bottle with Butane gas, will that help keeping the T-Max Developer longer ?

    To slow down development if you cannot get the developer cool enough during the summer.
    Warning!! Handling a Hasselblad can be harmful to your financial well being!

    Nothing beats a great piece of glass!

    I leave the digital work for the urologists and proctologists.

    that may help but as mentioned above, don't dilute it until you want to use it and only dilute how much you want. Say your tank holds 500ml (I work in metric!) and the the dilution is 1+4, then pour 100ml of developer into mixing container and add 400ml of water (ideally tempered to suit temperture required). Use once and dispose of.

    Sorry ezwriter, and even if you did the 1-4 once and let it set for a week, things likely wouldn't have went well. That developer doesn't keep well.... live and learn.

    You might have some luck with selenium intensification of frames you must have.
    I just selenium intensified a thin negative at least a full stop in density last year.
