"Mouse Nuts" is another reference point I oft hear bantered about. Insect/mammal discussion aside, I'd proffer that the gnat's buttocks be used for measurements in the < 0.010" range. And we leave the genetalia of the Order Rodentia to cover 0.011" to 0.100".
I'm open to more similies for measurements greater than a tenth of an inch.
What do gnats eat?
Perhaps this got started by instruction manual writers who wanted to be sure owners would err on the safe side when aligning the fence. If a sloppy tuner shoots for dead parallel, there's a 50% chance he's going to create a pinch. The more experienced person would probably decide for himself how to tune his saw anyway.
I'm relatively inexperienced. My fence has the prescribed toe-out, and it will stay that way until I see that it's causing a problem.

About 20 years ago one of the car magazines ran an article from one of their regulars about his trip through North Africa. At one point he watched some locals setting up an engine rebuild in which they measured the ring gap with a ruler. Of course, their gas topped out at about 68 octane so high compression wasn't an issue. I figure that I make enough mistakes without messing up on machine setup, so dead square it is. YMMV, especially if you're from North Africa. Bob
Tom notes:
It isn't the writer's fault. Check out your manuals. Notice all the skull and crossbone boxes telling you to keep your fingers out of places no sane person would put them anyway. Same with the slight toe-out (when I have to recommend it, I recommend folding a sheet of copy paper and using that as the measuring stick). It is based on legal liabilities in our suit prone society. First we need fewer lawyers. Then we need judges with the guts to toss out the bullshit cases without hearing them. And we need juries, for the stuff that goes to jury trial, that have sense enough to know that idiots should not be rewarded for idiotic behavior.
When all this happens, check out Cloud Nine. It's in Seventh Heaven, where we'll all be.

I agree that this can cause the problem, but it's not the case here. The locals playing with me agree the wood is straight.
It's a 30 day old WWII. Maybe I'll call Forrest and ask about them looking at it. But the other combos did exhibit similar behavior.
Wouldn't this show up on some of the other blades? We did this on (4) saws, a brand new General 650, a PM66, and two different Jet contractor's saws. The cuts made with the rip blades looked like they were scraped smooth, not a mark to be found.
Thanks! Barry
Thank You Bob, for causing me to fall out of chair at work... I'll laugh about that for days..
(I don't why it's funny, it just is)

No matter, what that gives you is a fence that is NOT parallel to the sawblade.
A better solution would be to put 1/32nd inch UHMW plastic laminate on or something like formica on the front half of the fence and leave the back edge of the fence bare to give the wood a little room as needed

There is none, the cutting takes place 90 degrees from the forward dead center of the blade to the fence. That is the critical area.
When I bought my Unisaw new in 1979, I just wished it had a vertical face on the rip fence! The dirty dog was splayed out top-to-bottom at the operator end. I built my own "T"-Square fence from 2" x 3" rectangular steel tubing and faced it with 3/4" x 5" white ash. I haven't aligned the blade to perfection (it's off probably 0.010 to maybe 0.020 across the diameter -- rough guess without measuring), but it is SWEET! I used polyethylene blocks as sliders for the T-square and it's as smooth as silk. Other than the junk fence that came with it, I LOVE my Unisaw.
