Dripfeed content membership levels and monthly subscriptions

So I have 3 subscriptions:
$9 per month
$22 for 3 months
$78 per year

What ever subscription they signup to they are drip fed content for the first 12 weeks 1 post per week so i read your article over at wpmu.org about drip feeding content and am trying to adapt it to my needs.

If they signup for a monthly subscription i need a payment to be processed after 4, 8 and the 12 weeks.

would the following work

Level 1-Welcome and Putting FINITE $9 7 days
Level 2-Short game FINITE $0 7 days
Level 3- Modern set up FINITE $0 7 days
Level 4-Swing needs to FINITE $0 7 days
Level 5-Wedge play FINITE $9 7 days
Level 6-Strategy FINITE $0 7 days
Level 7-Bunker play FINITE $0 7 days
Level 8-Mind tips FINITE $0 7 days
Level 9-Practice Routines FINITE $9 7 days
Level 10-On the course FINITE $0 7 days
Level 11-Special week FINITE $0 7 days
Level 12-Conclusion and future planning for success FINITE $0 1 day
Level 13- Premium SERIAL $9 30 days so they stay on the recurring $9 per month and still have access to the other premium sections.

The $22 per month will be the same but instead of a $9 payment monthly it will just be:
level 13- Premium SERIAL $22 90 days

Just want to make sure this will work before implementing.

Thanks in advance
