I love looking at this. 100 points is a lot but that only gives you a 57% chance of winning. 200 points is like 70%. 300 points is over 80%. 400 points is like 90%. 500 points is 95%. 600 points is 97.5%.

That's pretty cool. Thanks for sharing.

what?

This is your chance of winning. If you’re 100 points over someone you have a 57% chance of winning that game. That’s why you can’t feel too bad if you lose to someone 300 points lower because you only have a 80% win chance you’ll lose those occasionally. The interesting thing to me is that it stays pretty constant like if you’re 2400 playing a 2200 or whatever the draw chance just increases at higher levels

If I play Magnus at 1200 I have a 0.00000001% chance of winning that game. It could totally happen. I believe that’s one hundred millionth of a percent? He better not play me a hundred million games or he’s goin down.

It’s about 82% lose. 11% win. 6% draw. Should be a lot of problem. That’s why that calculators cool tho u can plug it in. So if they play 100 games the 1100 will probably win about 80 of them

Quick and dirty math.

This is a lost art in the age of computers.

Before computers, that is what a slide rule is created for. To do quick and dirty math. (Good enough approximations).

Slide rules had a marking for PI!
