I just finished a course and the instructor told me of an interesting article he had seen concerning ascent rates. The meat of the article was that divers were fairly religious in doing their 15' safety stop yet the average ascent rate from 15' to the surface was 200 fpm! I thought this seemed a little high until I started paying attention and noticed many divers popping up like corks following their safety stop. My only conclusion is they feel, "Ok, I've done my safety stop so I'm good to go." What are your observations and/or opinions?
