I thought that would be the prompt for this Danny, and with your requirements in mind, I think it's a sensible thing to take as many of the variables out of the equation. So - pick a temperature and stick with it - use the "sink as a water bath" method, at the standard temp. recommended by the chemicals manufacturer, and take it from there.
The flexibility of the black and white process means you have to do something prety darned silly to not get SOMETHING out of the soup, and back in the era of wet printing it was amazing how a good darkroom printer could make a image from often rather unassuming negatives, but if you're looking to minimise work in the "digital darkroom equivalent" then it's down to getting the best you can onto the film, and keeping it there with the developing - so you're going about the process in the right way IMO... Certainly most of the pro's who I worked with back when film was the only option had standardised processing worked out - at least the ones who didn't just hand the roll over to their trusted darkroom guy...
