Do you adjust your development times as time goes on?

I also got a bit of Aunt Mary's laundry, and Beau Jack, the dog, peeing on a fence, and a row of potted tuberous begonias on the porch and 78 trees and a million pebbles in the driveway and more. It's a generous medium, photography." -- Lee Friedlander
If my understanding is correct, replenishment does the following:

So, the simple answer is that no adjustment of times are required.

I'm not familiar with DD-76 could you explain the DD part? There is an FDD-76 which I believe is Photographers Formulary version.

Great thread. I'm an inveterate tinkerer; despite stellar results with Xtol, I have an unrelenting urge to fool with other developers. Partly this has been prompted by the declining amount of B&W film I am shooting these days, and the longer intervals between processing sessions. So I need a developer that does the job and lasts on the shelf--or one I can quickly mix from constituent chemicals--and requires no fuss to use. This odyssey has become expensive and tiresome, as I now have mostly-full bottles of DD-X (yuck), HC-110 (yawn), Xtol (hurry, hurry, might go bad), and others mouldering on my darkroom shelves.
Finally out of sheer exhaustion, I mixed up some D76H, which is D76 without the HQ and with bit more alkali (if I recall correctly). Dropping the HQ means no activity/pH change after a month of age so it's more predictable. I had not used D76 of any stripe in decades.
The results stunned me. Every film I've developed in it has been beautiful. The others are going into the waste bin--except maybe the Xtol--it's pretty darn good; and, well, maybe the HC-110 since it lasts longer than pharoah's mummy, and well....
Seriously, I've had my flings, sown my wild oats. Time to settle down with a nice girl who still has a few alluring tricks up her, ah, sleeve. (With apologies to the distaff frequenters of this forum. )

But as it matures and stabilises the time become constant, I keep a little notebook with times, replenishment and comments so I can monitor the results.
When I make up a fresh batch of developer I season it with some of the previous batch. I started doing this firstb while at school with Microphen, and have continued ever since with ID-11(D76), Adox Borax MQ and now finally Xtol. Now I keep my working solution in a 2.5 litre Plastic bottle using the other 2.5 litres as the replenisher, in the past with a commercial darkroom I used deep tanks.
This way of working is extremely economical, very quick as there's no solutions to make up each time and gives excellent results.

I too like D76. I've gone through a few phases, but generally stick to d76 and rodinal unless i'm pushing film. In that case it's acufine.
Never used XTOL, haven't used HC110 enough. Used to love pmk pyro (and would be receptive to using it again) and always wanted to use Harvey's 777 as well as mcm-100.
I think d76 and rodinal I like the most due to the results, ease of use, longevity in the case of rodinal and price.
i changed to d76 a half year ago. i´m verry happy mow because everything goes so easyly an my negs are getting better and better. for push i use tetenal emofin (i can´t say why, but i like it). most time i use t-max100 for 135 ,acros 100 for 120 and hp5 in both formats.
i like the tmax more than the others (i think its only emotionally).
the good thing is, that all this is only a hobby and i can make these things out of my stomach (so we call it in austria) and i must not look for the best quality (in the eyes of other persons).
but how one writer says it before, d76 is avaiable since a very long time, so it cant be bad.
I started with ID11 (same as D76 I'm told), but I'm starting to like Ilfosol. I think I just like the convenience. I can mix up exactly how much I need from the concentrate and it gives me nice negatives with FP4+. Made the mistake of trying it with HIE once though; ugh. Bad combination.

A couple of points:
Stock versus dilute - dilute (1+1 or 1+3) gives slightly better sharpness, slightly more noticeable grain (fine grain developer produces fine grain by dissolving the edge of each clump of silver, this action is slightly more pronounced with stronger [stock] dev.). 1+3 dilution has slightly more compensating action (slows development of highlights while coninuing to build shadow density).
Spot the difference - gets harder, the slower and larger the film.
Replenisher - if you add the recommended amount after each rackful (12 4x5" hangers, etc.) it should not be necessary to adjust development times. For anything but deep tank (15 liters) development, I would forget replenishment and use 1-shot technique.
Wnen I was a boy, D76 had the reputation of needing to stand overnight after mixing to stabilize - I haven't noticed this more recently
Yeah, the older you get, the more they seem to know!
