what do they mean by Advanced Spacing Algorithms, for those who tried the pro version
I think they’re thinking of adding algorithms like SM18 in the future, but since there’s no feature yet, we can only show SM2 to these advanced algorithms as an example.
I could be wrong, but I think it means you’re allowed to customize some of the settings of SRS. Like how long you see the same card if you got it wrong.
“Advanced” here means, comparing to the “default” algorithm, you could change the settings of algorithm according to your own needs,
