I found that just doing it once on the timeline worked for me. However I photoread more than 5 books on the topic. I suggest if you find some more books that you can do the timine installation again if you want. It's a case of waiting a couple of weeks and seeing how it works for you. You might find you want to do it again or that might have been enough.
I take each case as a new experience. I try it once wait and see if no result try doing it a few times (3 or 4 days with installation) then wait and see again a couple of week. If no results I'd look at an alternative... maybe borrowed genius would work better. try something different.
