 I'm not sure that tool will give me the proper chain slack due to the swing arm angle from my raised rear end.

I keep my chain adjusted on the loose side for that reason.

I thought that's why God gave us fingers?     My Scott oiler takes care of that - in that - it requires no adjustment for the whole season.  But then again, can you ever have too many tools?

I never adjust a chain using a slack number, too many variables.

I pull one of the shock/linkage bolts and jack up the swingarm to the point where the countershaft sprocket and rear sprocket are level. 

If I have any slack at this point then I'm good.

Yeah, it's more involved but it's also much more accurate and doesn't need to be done very often.

Yep, exactly!

We actually had a member loose the tip of a finger from a chain/sprocket encounter.

Ouch!!!!

That way you should never lube or adjust a chain with bike in gear

Hooli, having done this the first time, can't you then just eyeball (or measure if you're an engineer) the slack with the wheel once it's returned to it's resting position (off the ground) as a guide for subsequent adjustments?

When I was a little kid.we had a rear wheel drive tricycle. My older brother had it upside down messing with it. And he told me to feel the front sprocket with my finger. And then he rotated the pedals.He thought it was funny. Until he realized he. Couldn't rotate it back to get my finger out. So then he rotated my finger all the way around. Past the chain guard. Cut my finger all up. Luckily the chain was loose. Went in by my mom and she glanced at it and told my sister to clean it up and put some bandages on it. I was the last of 6 kids she was used to us bleeding am over by then.
