Deciphering Crucible data sheets

So, at the risk of exposing myself for the noob I am, I need ask a question regarding the data sheets on the Crucible web site - specifically, 52100.

It states for hardening:
Preheat: 1200-1250F (650-675C), equalize
High Heat: 1500-1550F (815-845C), soak 10 to 30 minutes. For vacuum or oil hardening, use the high side of the high heat range and soak times. Use the low side of the temperature range for water hardening.

Speaking literally (I do best with literal...), is this saying:
Heat your oven to 1200-1250F, then place your knife in. Let it come back to temperature, then ramp your heat to 1500-1550 and let it sit at this temperature for 10-30 minutes.

Based on the further notes, since I'm using oil, I'm also thinking the high side of both the temp and time ranges.

-Dan
