A lot of good opinions here, but I thought I would add one more.
Most of the guys at my field do some combination of full throttle for about 30 seconds, idle/full/idle/full, nose up full throttle.
After it's warmed up, I like to verify idle is solid for about a minute (I have also been trying to get my idle below 3000 RPMs if my Globee is to be believed). If you're idles is too low or your idle mixture needs help, idling for 1 minute and slamming it to WOT from idle will usually tell you.
Finally, I think spending some time at full throttle is also helpful to make sure nothing is loose or funky.
