A question about flash

I love the Nikon precision numbers down to a single digit in 40,000. I have not found my speed lights to be that consistent...maybe within a couple hundred at lowest settings...

Both longer and brighter as you add more flash powder. 
OR, BIGGER Bulbs. Loved that exploding foil.

My flashes have several power settings: Full, 1/2 1/4 and so forth all the way down to 1/124. Typically, how does a speed light control power usage? Do they Flash for a longer fraction of a second, or emit a more powerful, brighter light?
The power settings on the flash are the duration of the flash (the time it fires) nothing more (or less)!

When looking at speedlights, adjusting the power setting usually only adjusts the duration (tail trimming). A Nikon SB700 will have a duration of 1/1042 at full power, all the way down to 1/40000 at 1/128 power.
When looking at studio strobes and mono lights, as you adjust the power setting lower, it may be lowering the voltage, doing some capacitor switching (not all caps are fired at the lower settings), as well as a little tail trimming.
