I looked at the code check. The one 25% difference is in an intermediate variable (peak beds). The two differences of 10% are 39k deaths vs 43k deaths, and 100k deaths vs 110k deaths. The other differences are less than 5%. I can see why the author of the code check would reach the conclusion he did. I have given a possible explanation for the variation, that doesn't require buggy code, in my previous comments. An alternative hypothesis is that it's bug driven, but very competent people (including eminent programmers like John Cormack) seem to have vouched for it on that front. I'd say this puts a high burden of proof on detractors. https://www.nature.com/articles/d41586-020-01685-y https://www.nature.com/articles/d41586-020-01685-y
