Yes, the IFR has been consistently estimated at 0.4 to 0.7 since February 2020. 0.5% of 8B world population works out to 160M excess deaths. This calculation assumes availability of medical facilities at 100% with no dead doctors or nurses. I don't think our public facilities can handle so many excess dead bodies unless we let some float down the river. https://www.google.com/search?q=india+covid+19+floating+bodies+street+pyres https://www.google.com/search?q=india+covid+19+floating+bodi...

Comparing deaths on board with expected deaths based on naive CFR estimates from China, we estimated CFR and IFR in China to be 1.2% (95% CI: 0.3–2.7) and 0.6% (95% CI: 0.2–1.3), respectively."
