Note the temperature at 30 minutes.

You might be better off with O1 tool steel at 15 mins at 1475, then quench in oil from 120 to 130. What kind of oven do you have?
I have an electric lab oven, but it’s older and the heating coils are worn out so it needs around 2,5 hours to get it up 1520°F. I will have to time it to see how long it takes to get it from 1200 to 1520
