Review timing

When you submit a review and then submit one a week later, does that double the time you have premium access or merely reset the clock to began a week later?

The time ads up. You would have (12) weeks total in that case.

OP, go to your area where you can edit your profile and under "Your Control Panel" click (towards the bottom) on 'Paid Subscriptions' (under, 'Miscellaneous' and this will list BOTH Earned Premium Access as well as any paid subscriptions. Under 'Active Subscriptions' it lists your 'Premium Access (Male Only)', then 'Start Date' and the 'Expiry Date' and you'll see just what Darth mentioned above.
