following your theory my battery should be dead now.
Training the battery is known from old times of Nickel-based batteries, where it was almost a requirement. With Lithium batteries training in this sense is not necessary indeed, but a few full recharge cycles at the very beginning are helpful, because they help to balance the cell capacity. As you all perfectly know you Bold has a Lithium polymer multi cell battery. About specifics of that type you can read e.g. at
Lithium-ion polymer battery - Wikipedia, the free encyclopedia.
The rumor that you shouldn't ever let the Li-Pol battery to be completely discharged is a FUD. Each such battery has an integrated control mechanism, which shuts the battery down when a certain low level of capacity reached. So if you plug in the charger just after the battery went "empty" and load the battery 100%, there shouldn't be any problems. In this light I doubt the guide at
