## Day 100 of World Wide Covid-19 data.

## Finally, the **New York Times** published graphs that show the severity of the Coronavirus death rate compared with average weekly death rates. Here is the graph for New York City, which shows during the peak of the Covid-19 Crisis there were 6,000 more deaths per week than expected from the average weekly death rate, which was approx. 1,000.

## The death rate was 6 times the average death rate. That is a terrifying statistic and explains why we are all in lockdown or are slowly coming out of lockdown. Meanwhile, in the rest of the world death tolls are still increasing.

**Excellent Covid-19 stats update** **here**.

## Many statisticians are using 3-day and 7-day averages to track the Covid-19 death and infection rates worldwide.

## Mathspig is using the total average of deaths per day since stats were first published from 22 JAN 2020. When this average drops … that will be a sign for cautious optimism. But not yet!!!!

Mathspig grew up on a police station in the small Australian country town of Kyneton, Victoria in the 1960s. Australia has a very strict gun laws today. But such laws didn’t exist in the sixties. My Dad’s .22 rifle rested against our fridge. He pocketed the magazine.

**A .22 means a bullet calibre of .22 inches.**

**My Dad the Sharp Shooter** stopped a stolen car with one bullet. This was considered legendary by his fellow cops. He didn’t shoot the tyres. He managed, by accident and possibly even though he was aiming at the tyres, to hit the electrical lead into the car’s distributor cap. Phht! Car go no more. More on my childhood **here.**

**Sharp Shooter Maths**

One measure of the accuracy of rifles, riflescopes but also the sharpshooter is the MOA or Minute of Angle. The MOA can also be used to define the target zone (circle).

I cannot show you a triangle with an angle of 1′ because it would have to be 100m long on one side and only 3cm tall.

Needless to say, drawings are NOT to scale.

A sharpshooter can put 5 out of 6 bullets in a target zone drawn at 1′ angle around centre of target at any distance.

As the distance away from the target increases the target zone circle area increases.

A sharp shooter would be considered very skilled if they can shoot within a target zone (circle) of 10.5 inch radius at 1000 yds. Hitting a bull’s eye at this distance is down to luck.
