Ok, my lagers? I've had them stop bubbling in as few as 4 days. 5 is more usual. A long time ago I was in the 10 days 2 weeks length of time.Lots of healthy yeast, O2, nutrients in the boil shortened the time.
In the absence of a flow meter, aim for just enough flow that you can perhaps hear some bubbling and see a small disturbance of the surface.

No offense but if you have been brewing lagers for 20+ years, shouldn't you know what to expect?No offense taken! Yes, after 20+ years we generally have a pretty good idea as to what's going on. This one is taking a bit longer, with obvious signs of ongoing active fermentation, even after it's 9th day. Hence the question on average time for a lager.My star-date brewing logs are intact, so will browse to check on historical data.Never taken a hydrometer reading. Not one time in my brewing history. We always went by sound, smell, taste, and time. Surprisingly, it has worked for us quite well. I know this is blasphemy, and certainly I'll be labeled as a heretic!

Not a heretic, but perhaps an aspiring Luddite ? Being an avowed Luddite myself [flip phone and all] I suggest you do yourself a favor and spring for a hydrometer or refractometer. While it is wonderful to have sufficiently developed senses and the experience to successfully fly sans instruments, there is nothing wrong with adding accurately measured data points into your routine - you might be surprised by the results. If my understanding of Lager brewing history is correct, decoction mashing came about more because of an absence of thermometers with which to accurately measure temperatures than because of any special contributions of decoction offered over single infusion mashing. Some modern gadgets are worth adopting, a hydrometer is one I'd put at the top of the list.
