This clarification from Stephen on taking ELP's AFTER the initial ELP 1-9:
For clarification-
After you've completed 1-9 1 x you can take 10 while continuing to working on 1-9 multiple more times.
elp 1-9 is repeated at the same time elp 10 is taken for 2 weeks and then 11 for 2 weeks. 1-9 is repeated multiple times - and taken at the same time as the higher ones.
