Not that I'm echoing their thoughts, but I can only stress what they are saying.
Although alot of guides from steel companies can show a temp, remember this is a mean temperture for larger stock as it is rolled off the lines.
Smaller stock (like knives, small parts etc..) can be as much as 50-100 degree difference in my experience.
Also, as Brian pointed out, depending on how you harden can effect it (clay, full harden, edge harden).
Try tempering at 375 and raise it 25 degrees until you get the desired effect.
Everyones technique is different as well as what YOU want as a final result.
Experiment until you get it and "thats how you do it.."..
