I do this whenever I take a break of an hour or more.
    I posted a comment similar to yours earlier today but it obviously became a fatal victim in the big database crash. I can do nothing but completely agree with you. I have used this method for more than ten years and it works just fine. Sometimes I can keep the chemicals for more than a month. If I am about to make exhibition quality prints I use to mix fresh solutions, just to be safe.

    I have some proofs in the gallery today that was printed with 500ml dektol stock over a period of 11 days.

    The developer was left out the entire time, covered with saran in contact with the liquid.

    I printed maybe 75 proofs over 11 days, in 3 separate sessions.

    F5.6 for 10s, dektol at 75f for 90s on day one.
    F5.6 for 10s, dektol at 75f for 90s on day eleven.

    Developer at 75f has very little dissolved oxygen. Cover it with saran in contact with the liquid, where will the oxygen come from? For big trays, I cut up kitchen bags.

    Dumping it into a bottle, you might as well put it in a blender.

    I might add, eleven days is not the longest I've left dektol in a tray, and it was still good when I dumped it.

    I remember working in a darkroom where the stop bath and developer were left out all the time. At the end of a long day of printing, I'd dump the developer. We'd change the indicator stop bath them it turned purple and the fix when hypo check indicated when we had to dump the fixer.

    How much extra time is required to pour the solutions into bottles. I do it in 5 minutes.
