I guess I would prefer 6 stations, but because it spins easily past unused stations, it's not an issue. It's still a lot faster than a single stage because it's faster to flip to the next station than it is to swap cases in and out.
I use my T-7 in a couple different ways. I prep some brass with just two stages (re-prime/size, flare), three for some revolver ctg's (charge at the 3rd station). With those I don't go all the way around, I just back it up to station 1 while my right hand is removing the case.
With auto cases I use 5 stations (don't need a separate crimp, but that's what I do) and spin past the two unused stations. There's no wasted time or effort because my left hand spins it while my right hand is removing the ctg and putting it in the ammo box.
With .44 spl I use 6 stations , I add a pen light in station 4 to check the powder charge. Not needed for auto cases because my overhead lights shine into the case for powder inspection, then seat and crimp in 5 and 6. I don't stop at the pen light station, just pass through it so I get a good look at the powder. I refuse to seat a bullet without looking at the powder. (OK, I'm fussy)
