maybe it's the combination of the 2 internal clocks that give the effect?similar to the effect hfsg is getting?

and i did try a beer in the rack but they kept getting too warm,too fast.they must be COLD!and you must rotate stock!i only recommend this tweak for the adanced users.it is very time consuming and you must rotate beers exactly every 4 min. 23 sec. but on the upside:if you miss the rotation,you can always buy a clever little clock and go back in time to correct yourself!
