This is a review deck I have been studying(3rd time reviewing), I’m wondering how do I make 12h into 10 minutes and keeping all the other times(1 min, 1 day etc) the same.
You can’t set the hard interval directly. It depends on the steps (“good”-intervals) you define in the deck options:
If you press Hard on the first step , the interval will be the average of step 1 and 2 - Again and Good (in your case (2+8)/2 = 5).
If you press Hard on any following step, it will simply repeat the current step instead of moving on to the next.

In your case, I’d recommend you set the first step to 10. Pressing again will then show the card in 10 minutes.
