article in print that relates words to beat speeds, i.e. mississippi being a 
four beat per second indicator
How fast you say Mississippi depends upon whether or not you're from 
Mississippi ! Words like that are useful mostly for comparing rates rather than 
establishing them. With a good temperament system like the contiguous thirds, 
there's really no reason to know how to count 7.9463 beats per second, as everything 
is done by comparison. An F-A third is not the same from one piano to the 
next anyway.

For instance:
Tune A4, then A3 and A2. Most people can tune a reasonably usable octave, 
even without tests, but there are all sorts of aural comparison tests available 
to tune any type of octave that seems appropriate.
Tune C#3 about as fast above A3 as your watch ticks (if your watch is 4 bps 
like mine), or maybe barely faster. Absolute accuracy IS NOT essential at this 
step.
Tune F3 so C#3-F3 is a little faster. F3-A3 should be faster yet. Readjust 
only two notes, C#3 and F3, until the speeds seem to increase evenly. Even now 
don't worry about the absolute. 
Tune C#4 and F4 as octaves. Play contiguous 3rds over the two octaves. Don't 
count, just listen to the speeds increase. Extending it into the second octave 
like this usually makes mistakes start to stick out like a sore thumb. For 
instance, if you got the lower C# and F just a squeak high, there will be a big 
jump between C#3-F3 and F3-A3. A surprising amount of refinement can be done 
without any counting, but NOW you can use the Mississippi/University 4:5 
business I talked about in another post to get even closer. This is easiest in the 
lower octave where the beats are slower. 

I like to alternate between crude and refined tuning. Tune the octaves 
quickly until they sound good, then use the fine tests to nail them down, then leave 
them as anchors. Tune the thirds quickly, listen to what they tell you, then 
use finer and finer comparisons to nail them down and leave them. From this 
point on, you can't go very far wrong.
