Looks like you can’t directly, but presumably updated_after for a review wouldn’t change after it was created. If they were returned in chronological order, which may not be guaranteed, someone could get the first page updated_after 0000 on the day in question, then remove all the ones starting the following day.
Edit: ugh, but then have to look up all the subject id’s to turn them into items to display, which would mean yet another API call.
Each intensity represents a different range of reviews; you can see what each one is by hovering over the gradient key at the bottom.
Since my last reset (back to 1) I take 1 month breaks when the reviews start to pile up, to avoid those 400+ review piles in a day. Highest I have since reset is 331, so I’ll never get the highest color again if I can help it 
I would probably set my highest to 300, I do have that just enough times (but 250 might look even better). Hm, 50/100/150/200/250, that would be the perfect range for me! =D
With a map like that you could pose as a slacker. 
While I can definitely add interval options I think I’ll stick to just the five colors, meaning this is not possible, unless you want anything less than 50 to be the same as zero.
I meant like this: 0 - no color, and the 250 to be 250+, but I see I wasn’t awake enough to calculate it properly 
That would indeed be 6 colors. That wasn’t my intention. =P
Guess I need a different interval… Hm, 60?
I guess 0 (no color), 1-60, 61-120, 121-180, 181-240, 241+
I’d like to see this feature as well, if it’s not too much trouble to code. At the moment, I don’t have any days where I had over 400 reviews. In fact, other than one 300+, the rest are all below 250.
If it were user customizable, I would probably go for something like:
0 / 1-50 / 51-100 / 101-150 / 151-200 / 201+
Just out of curiosity, why did you go for increasing sizes for each group rather than a constant size like I wrote above?
P.S. But really, I am most excited about this:
It felt natural to me to do it that way; the colors still keep a constant relation to each other (2x the last one) and they still manage to differentiate between light, medium, and heavy workloads. I think it makes good sense for a default. If 200+ were the last interval then I know most people would very long periods of the same color. I will add the option, however.
I personally think this logarithmic increase is much more natural.
The difference between 50-100 reviews feels much greater than the difference between 250-300
You could reset to 1…
What? The Durtle Heaven thread has ground to a halt too, so what else could there possibly be to do if not Japanese studies?
New update!!! All them colors! =D
And lessons! =D
I also only changed one number in the setting, the max on reviews from 400 and down to 300.
Lessons are on intervals of 10 =)
Interesting color choices… to say the least
It’s a passage from light blue to red. Lightblue for those light days (almost white), blue, darker blue (but I’m a sucker for teal, so it has a bit of green in it), purple for intense days and then red for those extreme days =P
If not for the bit of teal it would have been a natural gradient from blue to red
Ehm… Work more on Durtle Heaven? I have a plan, trust me not
Lessons (Intervals: 5/10/15/20)
In July 2017 I started using Lesson Filter, so the lessons counts became very regular.
Wow, that is very regular on both! =D
Oh hey is today your birthday? 
Congraaaaaats!!!
