I find I get 3-4 good minutes of shavings at a stroke every 5-8
seconds, and then I need to advance the blade just a fraction to keep
shaving.

I pulled the blade tonight and it will no longer shave arm hairs.
Definitely has dulled, but I will try again after I rehone the blade and
when I advance it the second time I will remove the blade to test
again.

Yes, many hard woods (not "hardwoods") will dull an edge fairly quickly. Try
wengé or panga panga and you will express stand time not in minutes, but in
strokes.

Advancing a blade will work because a plane will work reasonably well with
even a somewhat dull edge.
