ATS 34 reheat treat

I am needing to re-HT a blade of ATS 34 and was wondering what should be done beforehand. Do I need to anneal it, normalize it or just go right to the oven (with foil) and redo my recipe? If one of the first two, what temps & times are recommended?

Thanks
 
I would just go back in the oven with foil at 1975 for 30 min and plate quench in the foil. I get 61-62 this way.
 
I temper at 400 twice, but I HT at 1900 with a 30 min soak. I would assume that Bruce's temper temp is different since he HT's at a higher temp.
