Pick an average and determine how many strokes of the file it takes

that one sharp. Give all the others the same number of strokes. Go
cut wood.

Where's the "cut in a semicircle because you didn't keep the angle
consistant between the left and right teeth" step?

That was not the focus of my reply but.

Several reasons why the saw wants to cut 'in a circle'.
Tag a rock or a nail and do more damage to one side of the chain than the
other.
Worn bar.
Improper sharpening.
Sharpening (by hand) takes practice.
Unless the technique is severely bad the 'cuts on one side' thing won't show
up until after several sharpenings. Then the only thing to do is re-sharpen
in a jig or hand the job off to a sharpening shop.

Taking it little further. Has anybody had the joy of splitting Dutch
Elm?. I swear that the grain is braided and bonded to itself with some
kind of resin. Some varieties (Ontario) are incredibly tough to split
even when notched with chainsaw.

Oh yes! About 30 years back when Dutch elm disaease killed nearly all our
elms, I had two dead elms on my patch , each over 5 feet in diameter -
what an absolute b*stard they were. I ended up cutting them into blocks
with a chainsaw - I lost count of the number of times I sharpened, & must
have got through 3 chains. I remember my mate coming over with hius
Kubota diesel mini tractor (about 18hp) which was fitted with a splitter
driven by the PTO. It consisted of a table with an enormous woodscrew
about 4 in diameter which wound itself into the blocks. We had to pilot
drill with a 3/4" hole before it would look at them & we finally gave up
when a block jammed on it & stalled the tractor!!! I had to chainsaw the
block off the splitter! I let the second one rot on the ground for 20
years & burned it in situ.

Elm has interlocking grain, kind of like the toy chinese fingercuffs,
which makes it an absolute bitch to split. This made it the perfect
wood to use for wagon wheel hubs in days past.

I am surprised that you have any hearing left. I can't stand to be
around a chain saw at all without hearing protection. I did it as
a kid but not now.
Wasn't the saw that did it Chuck...it was a foundry and something to do
with being a loader on a five inch gun and a pointer/trainer on a 40MM
"ack ack"....90% loss of the high end.
