Discharging battery

HiI guys, i just wondering to know about this issue. That some people says it can defect your battery by completely discharging it and then fully charging it, in the other hand, some people says that is the way you recalibrate your battery

Any suggestion?

From the Apple website .....


'..... be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).'
