Nice comments guys....
Jeff,
It appears that you were correct...at least in my case. Like I said, very consistant from arrow to arrow...and it showed an expected difference from one bow to the next but it was much slower than I anticipated. How much slower you ask? Well, at a 30.25 inch draw length and a 70 lb draw weight with a 430 grain Beman ICS arrow and my typical loop setup and peep (tubeless) on the string I was only getting speeds in the 263-264 fps range from the Liberty....and only around 275 fps with the same setup on the MM....
Ausie,
I promise I won't shoot it.

I don't have your fascination with speeds down range...
BG,
Now, is that 10fps going to be consistent or is it going to be a percentage of error?
Exactly. I would not feel too confident not knowing which.
Oh, and that 122 was with both the Bowtechs and a Hoyt....

....now where can I find a Mathews just to make it a clean sweep all around....
WWAG,
It is funny you should mention that...

. How many chronos should I go through before I am happy with the speed results? [8D]
On a related note I tried the Radarchron at different distances from the front of the bow via some different stabilizer combos and the various slots on the adjustment bar that comes with the unit (even put it out at farther than 3 feet with an X7 target stabilizer I had laying around) but the reading pretty much stayed the same from shot to shot and bow to bow.
Well, I ordered a pro chrono and had it overnighted so I should have some more to tell on Thursday....
