One thing you may notice is the UK, Belgium and France (plus a few others) are showing very similar figures for Covid vs Excess which means they probably have good, honest and accurate systems to record and share data across our healthcare settings. Some others look wildly different (US, Russia, Mexico, South Africa, even Germany) and this shows they are either a bit slower or have a less open data sharing environment.
Those numbers you see on the worldometer site should be taken with a bucket of salt, but they ARE okay for monitoring trends.
