Added a fancy chart.md

[Expertium]

It illustrates how workload changes with retention.

[L-M-Sherlock]

I think it would be better:

[Expertium]

I was using 1/interval to approximate the workload. If you want to take into account the fact that for lower values of retention, workload increases due to the user having to relearn more forgotten cards, then this probably will require using the simulator to make an accurate chart.

[L-M-Sherlock]

OK. I will draw one with simulator.

[Vilhelm-Ian]

I don't get this chart. The optimizer gives different values for a smaller workload

[Expertium]

As I said, I was just using 1/interval. This takes into account how intervals themselves changes, but doesn't take into account the fact that as intervals become shorter, the user has to re-learn more.

@Expertium, could you help me draw one with above data?

[Expertium]

You mean with colors? Ok, I'll do it later.

[L-M-Sherlock]

You mean with colors? Ok, I'll do it later.

I mean the style of your original chart. Thanks!

[Expertium]

Is workload in minutes or reviews?

[L-M-Sherlock]

It's in minutes. However, it's better to keep the specific values hidden and only show the relative sizes on the chart.

[Expertium]

It's in minutes. However, it's better to keep the specific values hidden and only show the relative sizes on the chart.

I agree about not showing exact values, but I think it's best to specify what units (time or reviews) is workload measured in

[Expertium]

Also, mention that the exact shape of the curve depends on the user's parameters and habits.

[Expertium]

Oh, and I also recommend adding the add-on compatibility table to the second guide (about built-in FSRS) too.

[L-M-Sherlock]

Could you update this branch? I will merge it.

[L-M-Sherlock]

Oops. The chart seems misleading. Do you set the y axis' intercept to zero?

[Expertium]

What do you mean?
Ah, ok I see. Yeah, it makes it seem like the workload will increase from barely above zero to much higher values.
