"Too slow" "Too slow" "Too slow" OK, this is clearly not meant for trackpads. I can see how I might do it reasonably in the given time with a mouse or on a tablet... but not on my laptop trackpad!! :S

I'm doing it on mobile and while I could go faster, I..... don't want to? So I also got the "too slow" and along with that, got bored

I was wondering why some circles seemed great but got low scores. To test your tip, I just made a square and got 92%

My anticlockwise circles score more than my clockwise ones. Is there some theory behind that ?

Same here, and I always write the “a, o” clockwise. I was surprised to see my circle drawing skill is better anti clockwise :-)

Reminds me of a side project of mine called “Imperfect Circle” which makes asymmetric swung beats https://circle.jminjie.com/

Brilliant! Add a controller for adjusting directions from 4 to more or less and I can start my new band!

got 94%! macbook trackpad (and a couple dozen attempts)

Close: My circle is 90.0% perfect, can you beat that? https://neal.fun/perfect-circle/ lol

My circle is 91.0% perfect, can you beat that? https://neal.fun/perfect-circle/

One of my maths teachers was able to draw up to something like a three foot circle on the blackboard that looked very, very close to ideal every time. He would always use two arcs to do it and it was uncanny. He would whip out a metre/yard rule to do straight lines because they are much harder to do. Your limbs etc are all a collection of ball and socket/downright weirdly jointed/hinges with benefits/more weirdness.…

At my university the math department held an annual chalkboard circle drawing competition.

I am imagining I somehow have a hidden wire up my sleeve creating the radial tension for a perfect circle

Fishing line attached to a collar around my shoulder could could work

On a completely different note, in grade school I figured out you can tie fishing line to a pencil and wait for someone to try picking it up. Then give a little jerk so it moves 10 inches or so

People react wildly differently when they suddenly see behavior their mind cannot process! One math teacher walking around the back of class literally jumped up and a gave out a loud “Ieeeyaaa!” shout.

We can react to something much faster than we can think it through

My middle school maths teacher (awesome guy, also had a mustache - mid 90s) taught us how to draw (large) circles on blackboards easily: Start from the bottom and go counter-clockwise full circle having your arm fully extended. After the first couple of tries, when you build up confidence through the results, the circles get very good. The trick is not moving slowly, but doing it in one go. The 3'/two ark circles he…

I wonder if standing sideways helps too

Do it with a track ball. That'd be hard mode

Extreme mode: the keyboard arrow keys

Definitely not going to work with the timer
