discussion question about VoiceOver

I am always so fascinated by people who can understand VoiceOver at higher speech rates. I want to hear from those who had their speaking rate at a certain setting for a while but then worked their way up. How did you do that? How long did it take you to adjust? I was at 70 percent for a while with Eloquence, and trying to train myself to get to 75 because I'm convinced I could get more done faster if it's talking faster. I can understand it, but there are times it does get overwhelming. I love these types of questions because I find it interesting how we all process things differently in terms of auditory processing. Let's see what answers I get!
