Yes, I agree, only it's not about the percentages alone. I'll quote from my post from April (1) which was already in the context of Covid-19, where I quote the start of the presentation by Al Bartlett: https://www.albartlett.org/presentations/arithmetic_population_energy_transcript_english.html https://www.albartlett.org/presentations/arithmetic_populati... "It's a great pleasure to be here, and to have a chance just to share with you some very simple ideas about the problems we're facing. Some of these problems are local, some are national, some are global. They're all tied together. They're tied together by arithmetic, and the arithmetic isn't very difficult. What I hope to do is, I hope to be able to convince you that the greatest shortcoming of the human race is our inability to understand the exponential function." That's why when some hear that R=1.2 can be catastrophic and R=1 can be fine they just switch off. And there is exactly that "only 20% percent" difference. But many developments in nature that work against humans have exponential behavior, including the stuff that humans do. Somebody once named the video of that Bartlett's presentation "The Most Important Video You'll Ever See" and in this case it's not a clickbait.
