Ugh. Please abandon this opinion.
Did athletics records fall ANNUALLY through about the 1980's? No. The same is true for cycling. The trend is, roughly, if a new, more effective training method is found, then many records fall. Then things grind along until the next innovation.
Please don't apply this concept to modern athletics.
