I never said that.
If that is what was referred to in your post it certainly was not clear. I thought it was in regard to your claim that Sine Wave was not universaly accepted by ITF orgs., vis a vis a poster not being representative of the ITF curriculum.
I highly doubt that it was a permanent part of ITF in the mid 70s, as some here would have led one to believe.
