Please see batteryuniversity.com for their article entitled
"Battery Fuel Gauge: Factual or Fallacy?"
-- scroll to "Calibration".
This gives a full rationale for occasionally discharging until Kindle asks for a recharge.
That page shows the correct, complete procedure:
1. Charge fully (sets the 'full-charge' flag)
2. Discharge to 10% (manufacturer will specify the exact percentage; here it is shown as 10% -- sets the 'full-discharge' flag)
3. Charge to 100% (to complete the calibration).
EDIT:
4. Discharge to storage (40%) or standby (80%) capacity.
With Kindle, discharge is (somewhat) equivalent to ordinary use of the device, so it's a bit tricky to get it down from 100% at much of a discharge rate. The user will therefore want to time the calibration procedure to coincide with the beginning of a heavy usage day for Kindle.
