Hi Iam,
1. I equate Speed Reading with Rapid Reading. From that perspective, yep I Speed Read.
2. I tried Speed Reading before PR. I used the Evelyn Wood book and the Tony Buzan. I just found them frustrating. My speed may have increased but it seemed like too much work and seemed to tire me out.
3. I have noticed a very marked increase in my reading speed since taking up PR. Even at the beginning, I found that I moved through books much more rapidly. This was true even of books (fiction) that I didn't PR first. Perhaps I had begun to integrate the tangerine technique and getting into state. I cannot, however, offer quantifiable data. I can only tell you subjectively that I was moving through books at a faster rate (and I wasn't looking for it to happen--I was surprised by it).
