Where are you testing on the blade to get that hardness?
Did you get a spec sheet with the steel?

The second consideration is how quickly you were able to get the blade to the quench. You have very little time to do this and if you were to delay for a few seconds the blade could drop below critical.
The last situation is that it is difficult to work with a closed oven. Blades tend to scale and decarburize in that environment. You might possibly have some decarb and that would through off the RC test.
Last you did not mention tempering. If you tempered the blade what times and temps were involved?
