Cyclone,
Those pictures made me notice something....This thread may have just saved me from being extremely pissed off.
Good stuff guys.
Always glad to be of service. When I can't shoot, I take out my giant "file-folder 'O truth"

and read about the .22's I oughtta be shooting! Suffice it to say, I've been waiting to share those pics for sometime.
To me, the most useful thing I noticed was the 1st URL's "rules" for ammo comparison - they make sense, and work!
Here they are, by the way:
1) State the particulars (i.e. distance, target types, rifle, scope, rests - and ammo type, of course!

). Added thigs like wind speed and temp are nice, but a bit show-offy, perhaps!
2) Ensure you are testing the ammo you are testing (i.e. test by first firing "clearing shots" to acclimate the barrel to the particular ammo, and only then "print" your shot patterns. The clearing shots are to remove any lubrication/schmutz left over from previous bullets, or to build up lubrication that is on the test bullets

).
3) Added-point: Two swipes of a boresnake between ammo-types is recommended.
