Qpoints earned within any 12 month period count towards determining if your membership qualifies for a tier upgrade.
Once your membership tier is upgraded, you will require less Qpoints to renew your membership tier. Qpoints earned over the last 12 months or the last 24 months are considered to determine if you have met the criteria to retain your membership tier.
The following chart shows the number of Qpoints required to upgrade and retain your membership tier
