I wonder how hard it would be to write a program that analyzes accuracy rather than time-per-move?

Eh, maybe. If we assume a game is 40 moves, then...
Each image is 50 games which is about 2000 moves.
All together I did 1000 games for you, so 40,000 moves(!)
Having a few over 1 minute doesn't really mean much IMO. Maybe someone interrupted you, or it took extra long to change to a song you like you youtube or something heh.
True, but I estimated about 20 minute-plus moves. I can't be sure about that number, but if it is accurate, that means I thought for a minute once every other game in a 100-game span!
1 out of almost 5000 of your moves took more than 1 minute.
All together your shape is this:
-

Which I agree is just a tiny bit slow. Maybe because I mostly looked at higher rated players (remember I was trying to get cheaters) but usually 1 second was the most common, followed by 0 seconds (premoves). You have 2 seconds as your most frequent and premoves as your 5th most common.
For comparison B1Z's blitz games are this:
-

... see what I mean when I say all the shapes are the same? lol
Except of course for [cough] certain types of players
Cool! I guess I need to manage my time a little better. Thanks for taking the time!

Guys in the cheating forum have been doing that for years... but you probably already know that.
The guy I was annoyed with (and who eventually got banned) seemed to be using a weak engine. The type and number of errors was very consistent and looked human to me... but when I graphed his move time about 70% of his moves fell within a 3 second range. For most people the standard deviation for 10|0 games is about 10 seconds.
Since chess.com wasn't banning him I was trying to come up with compelling evidence by showing his graph matched already banned cheaters and didn't match honest players.
OFC they ignored me because this system is completely unproven (how reliably does it flag cheaters? What's the rate of false positives?) But I tried my best, and luckily he was eventually banned.

Here's an anonymous user whose graph is a little different
These were 2500 rapid games played over 1 year, so some rating improvement is definitely expected.

My graph would likely different be from the rest. Maybe it peaks at 5 seconds perhaps. Though I'm not too certain about this.
I also wonder how blueemu's graph for his daily games would look like.
Maybe the program could be modified to display number of hours instead of number of seconds in this instance.

I... actually don't know what the .pgn of a daily game looks like lol. I have no idea how much code I'd have to change to make it work for daily.

Meh, everyone who's said they think theirs is different turns out to be the same, but sure, why not, I can check heh.

Worth a try... but with Daily games you are only concerned with moving before the three-day limit expires. There is no running tally of time the way there is in Bullet, Blitz or Rapid.
That was why I suggested an analysis of accuracy instead... it can be applied to Daily just as easily as Rapid.

@eric0022
Your standard deviation is about 12, meaning about 70% of your moves are between 0 and 11 seconds.
Since all your games are longer than 10|0 this is pretty much exactly what I'd expect, the shape and everything, lol 
You actually took so fast to obtain my 70 games! Yup, My graph looks a little different from the rest.
EDIT: Ok, maybe not so different.
Blueemu has a point there.
If I plot a graph of accuracy...my accuracy graph will likely peak at 0% to 10%, considering that I make blunders very often.

I believe @mgleason wrote a small program that automatically analyzes batches of games. T3 or T5 analysis and all that. You're a member of the cheating forum, you could ask.
I'd have posted this topic in that forum, but accounts newer than 1 month aren't allowed heh.

You seem to write a lot of programs, where do you write them (like github, or...), and how do you get it to display graphs, i.e. how do you use a program to download games from chess.com and then analyze that stuff, and display it?
while I may not be op,
it isn't too hard if you have a good grasp of matplotlib, and other python datascience libraries such as pandas
I'm struggling with my irrational dislike of python (because it's so easy to code things compared to other languages, such as my preferred c++) and this isn't helping (lol).

One time, I cheated on my calculus formula quiz. And I think I have one tomorrow... maybe? I really don't want to memorize trig derivatives/integrals.

Update I think I did pretty good on my formula quiz although I forgot arctan

It's so mean they make kids memorize that stuff... as an adult you're free to look up anything

hmm...i started to like mathematics when i discovered "3blue one brown".
Ok, this is kinda boring when they all look the same.
