TVs were set up so that even if there were low power situations the viewer would never see the edges of the picture. (When there was lower power delivered to the TV, the picture would shrink.)

I looked at the other specs from some of the other broadcasters and PBS seems to be the widest in respect to safe title and safe action. I've also seen 90 and 85. Personally, with modern TVs, 90% and 93% might be pretty generous actually. I wouldn't doubt that it could come down to 95% for BOTH in reality. Also, with all of the repurposing of programming to the web, there's no reason to have safe title at all on that content, so unless you want to produce two versions, the less safe title the better - by that I mean the less DIFFERENCE between full raster and safe title... actually the BIGGER safe title is the better.
