RCT does not simply tune set octave types, as some seem to be suggesting - it creates a smooth curve, balancing it from section to section to fit in with whatever octave type you want.  So if you want a 12:6 octave type in the first octave you set that, and then you can choose slightly narrow or wide very easily with software 'sliders' in custom EQ. It's really very fast and easy, and is done after sampling the piano so that you actually fit the individual piano scale. Another benefit of this adjustability is that if, while tuning the piano, you find that your usual octave type doesn't fit this piano well (like maybe if that slightly wide 6:3 needs to be wider), you simply pop back to the custom EQ screen and change it again.  Takes a few seconds. RCT also remembers your settings, so that on the next piano your octave tweaking will still be applied to the new measurement.  It is good to look at it again and make sure the octave tweaks still make sense after measuring a new piano, but only slight changes are needed from one piano to the next. By the way, I think that calling RCT a "single partial" device is a little misleading.  The software  listens to all partials together, and balances the coincident partials into a tuning, just like the ear does.  Besides the number of samples used, the difference between RCT and Verituner seems to be (as Ron's wrote) that Verituner adjusts to partial strengths, while RCT give preference to the octave type that the tuner has chosen.  Both approaches will give good but slightly different results - which results are "better" becomes a subjective argument that each tuner needs to answer for him/her self.
