Criteria for deciding when to sharpen

Bill Tindall, E.Tn.
"My intention is that you should be sharpening much more often, alloy or no alloy. There is no other way to get the best use out of your plane."

First, thank you for the thoughtful response. But I need more to make it functional. Let us focus on some practical task that I do. To repeat I don't plane surfaces for appearance. I am after wood removal without tear-out. If wood goes away reliably I am content, ...maybe too content? Whatever surface is left will get sanded, stained and finished with a finish that builds- conversion varnish, conventional varnish, a substantial build of shellac, etc.

Example- I assemble a M&T frame. I reach for my trusty #5 Stanley to level the slight irregularity at a joint intersection, or leveling a drawer divider. Can't remember what I last used plane for because it was a week or two ago. I plane and a shaving develops. I am happy and continue. If I am still picking up a shaving when I am done I put the plane away for another day. When the plane doesn't pick up a shaving I presume it too dull and sharpen.

So, you advise me to sharpen more often. Ok, you have credibility because I know you face similar planing tasks. You got my attention and I am listening. But you have not advised how I determine when to sharpen to achieve the unexplained benefit from doing it more often. My definition of a plane working is wood going away without tear-out. Is there a reason that I should have another standard?

Not picking up a shaving or tear-out are signals I can see. So far I have not seen the signal you use that comes before these signals that you say are too late for me to "get the best use out of your plane".
