I was surprised to notice this change too, but mistook it for my clock being off. The smaller 15 minute more accurate reviews were handier for planning when to come back. Look at the clock: oh, 4 hours later. Easy.
I am not into that. Then again, I was not into the last step to Guru going down a day either. All this shortening to the SRS has left me not flexing my memory muscles as much…
@Viet @Koichi is there a scientific reason for this change? Or to just make programming/server loads easier?
